Care

General Care & Storage
To get the most out of your Petszo delivery, please keep the following in mind:

  • Edibles: Keep food and treats tightly sealed and stored in a cool, dry environment.
  • Fabrics & Beds: Gently wipe clean or wash at 30ºC (always check the individual label first). Do not bleach.
  • Safety First: Regularly check toys and accessories for damage and remove them if broken.
  • Note: Always refer to the specific packaging for exact instructions.

Getting the most out of your Petszo order comes down to storing things properly and checking them regularly. Here's what matters.

Food and treats

Keep dry food tightly sealed in a cool, dry place away from direct sunlight. Resealing the bag or transferring it to an airtight container helps stop the fats going stale, which is the usual reason a dog or cat suddenly goes off a food they previously liked.

Opened wet food should be covered and refrigerated, and used within about 24 hours. Serve it at room temperature rather than straight from the fridge — cold food is noticeably less appealing to most pets and can be harder on sensitive stomachs.

Many treat pouches contain a small oxygen absorber sachet to keep the contents fresh. This isn't edible — remove and discard it before giving your pet the treat.

Beds, blankets and fabric items

Most fabric items can be gently wiped clean or machine washed at 30°C, but always check the individual care label first — padding and covers vary between products. Don't use bleach, as residue can irritate skin and paws.

Removable covers are worth washing more often than you'd think, particularly for pets with skin sensitivities.

Toys and chews

Check toys and accessories regularly for damage, and remove anything that's cracked, split or losing pieces. Small fragments are a genuine choking and blockage risk.

Always supervise your pet with chews and rawhide products, and take away any piece small enough to be swallowed whole. Match the chew size to your pet — a chew intended for a small dog won't last long with a large one, and creates more risk.

Harnesses, collars and leads

Check the fit periodically, especially on growing puppies and kittens. As a rule you should be able to slide two fingers comfortably under any strap — tighter risks rubbing, looser risks your pet backing out of it.

Inspect stitching, buckles and clips for wear, and replace anything showing damage before it fails on a walk.

Litter trays and small pet enclosures

Scoop clumping litter daily and top up as needed; a full change every 1–2 weeks is typical, more often with several cats sharing a tray. Clean the tray itself with hot water and mild detergent rather than strong disinfectants, some of which are toxic to cats.

For small pet enclosures, spot-clean soiled bedding daily and do a full change weekly.

Switching foods

Introduce any new food gradually over roughly 7–10 days, mixing increasing amounts into the current food. Sudden changes are one of the most common causes of digestive upset, and it's easily avoided.

Always check the product packaging. The guidance here is general — individual products carry their own storage, washing and feeding instructions, and those take precedence. If you're unsure about something, or your pet has a specific health condition, speak to your vet.

Delivery

How long will my order take to arrive?

We aim to dispatch orders within 1–7 business days of you placing them. Delivery time after dispatch depends on the shipping method chosen at checkout. You'll receive tracking details by email once your order is on its way, so you can follow its progress with the carrier.

Do you offer free delivery?

Yes — delivery is free on all UK orders over £59.99. Orders below that threshold are charged at the rate shown at checkout before you pay.

Where do you deliver?

We currently deliver within the United Kingdom only. We don't ship internationally at present. Please note that a small number of items are shipped from outside the UK and may take a little longer to arrive — this is noted on the individual product page where it applies.

What if my order is late?

Carrier delays occasionally happen, particularly around public holidays or in bad weather. If your order hasn't arrived within the expected timeframe, get in touch with your order number and we'll chase it. If a package is confirmed lost or significantly delayed by the courier, we'll send a replacement or issue a refund.

How do I track my order?

Once your order ships, we email you tracking details. Use these to check live delivery status directly with the carrier.

Returns & refunds

Can I return something if I change my mind?

Yes. Under UK consumer law you have 14 days from receiving your order to tell us you'd like to cancel, and a further 14 days to send the items back. Items need to be unused, in their original packaging and in the condition you received them. Return postage for change-of-mind returns is at your cost. Full details are in our Refund & Return Policy.

What if my order arrives damaged or incorrect?

We'll put it right. Under UK law you have up to 30 days to reject a faulty item for a full refund. For transit damage, contact us ideally within 48 hours of delivery with photos of both the item and the packaging. We cover return postage on faulty or incorrect items and will offer a full refund or a replacement.

Are there items I can't return?

For hygiene and safety reasons, opened or unsealed pet food and treats, used grooming products, personalised items and gift cards can't be returned unless they're faulty.

How long do refunds take?

Once we've received and inspected your return, we'll let you know whether it's approved. Approved refunds are processed within 14 days of us receiving the goods, back to your original payment method.

Can I cancel an order before it ships?

Yes — email support@petszo.co.uk with your order number any time before dispatch. If it's already gone out, you can return it under the 14-day change-of-mind period once it arrives.

Products

Do I need a prescription for veterinary diets?

No prescription is legally required in the UK to buy veterinary diet foods. However, these products are formulated for diagnosed conditions, so we strongly recommend speaking to your vet before starting one — and having your pet checked at least every six months while feeding it. If your pet's health worsens, seek veterinary advice straight away.

How should I switch my pet to a new food?

Gradually, over roughly 7–10 days. Mix a small amount of the new food into the current one and increase the proportion each day. Switching abruptly is a common cause of digestive upset.

How do I store pet food once it's open?

Keep dry food in a cool, dry place, ideally resealed or in an airtight container to stop the fats going stale. Opened wet food should go in the fridge and be used within about 24 hours. Always check the individual packaging, as some products have specific requirements.

This policy explains how we process, dispatch and deliver orders, and what to do if something goes wrong.

We aim to dispatch orders within 1–7 business days of the order being placed. Business days are Monday to Friday, excluding UK public holidays.

Once your order has been processed you'll receive a confirmation email, followed by tracking details where available.

If a package is confirmed lost or significantly delayed by the courier, we will send a replacement or issue a refund.

Best harness and price around!

Always compare other places but PetsZo have the best price and the harness never lets me down.\nStrong, resilient and lasts a fair few years for a dog that pulls A LOT. My jack Russell has been through so many different harnesses, but this one is by far the best and PetsZo offer grate range of colours and sizes. The only down fall which is why I have to order a new one,is the hook the lead attacheds to, the material has ripped but the harness lives a hard life and don't regret having to reorder

Great harnesses, BUT NOT FOR EVERYONE!

Have lots of experience with these harnesses.I use them at work, too. They're either the best thing you've found or just completely useless item.\nMake sure you measure!\nGreat for scared dogs to get them used to harnesses as it requires minimal contact as you don't lift any legs!\nHowever, terrible for harness-escape-masters! They can slip them off without much effort. Use double-ended leads= clip to the collar and harness. \nIam yet to see dog that would stop pulling purely because of it.

Harness came off whilst walking

Sturdy but still came undone completely when out walking for the first time! Think the velcro is shiny and not rough enough to adhere properly the first few wears. Otherwise happy with it.

The Best

Just the best Harness money can buy. Strong, quality,hard wearing. Would never use any other harness again.

Absolutely Amazing

I've got two big dogs, 60kilos each, one as good as gold (usually, but not where cats are concerned) one a monster and these harnesses keep them both safe and secure. Easy to use, dogs like them and are comfy in them and it gives you complete control when needed. The top handle on the harness is an absolute godsend, extra grip when necessary and keeps the dogs very close to you, should you need to pull them into you for whatever reason. So worth the money!

Awesome, A Must Have Harness!!!

Got 4 of the Julius K-9 harnesses for my 40kg GSD, my nans 60kg and 46kg mastiffs and my mums 13kg Frenchie and they were the best udea ever, the frenchie doesn't choke when pulling anymore and the GSD gets walked on his collar but the harness is great for in the car and for when we're on a walk and I need to get hold of him there's a very useful handle on the back for me to grab. Highly recommend for anyone looking for a decent harness at a decent price. Best item I've ever bought for the 4 of them xx

Love it! So sturdy and hard wearing!

Love it! We bought this for our Old English Sheepdog last year for Christmas, and it is practically in the same condition it was when we bought it (just a lot muddier). Nothing is coming un-stitched etc. Only thing that has gone wrong, is the little pop stud that holds the flap down over the handle has rusted and doesn't hold anymore, but that is a minor detail. \nIt is easy to keep clean, everything still reflects and glows on it like we should! It holds back our 37kg baby magnificently! :)

Why have I only just found this product!

Notorious puller JRT. Now I have only discovered this amazing harness! Why after only nine years of suffering! My arm has constantly been pulled out of socket! :D Done various training to correct but never worked. I guess thats a terrier for you.The difference was instant, he has never walked as calmly like that ever in his life. The harness itself is very well made, good quality. Looks to be comfortable on my JRT. Recommended!

Perfect fit

Got the mini, fits perfectly for a 5 month old French Bulldog and plenty off leeway for when he gets bigger. Good comfortable harness, fits securely around him. Good price & quick delivery from PetsZo. Thank you.

VERY happy!

Wish I had bought one of these years ago. Dog loves it, he doesn't realise he's on a lead and walks in a more relaxed manner without pulling. Very comfortable well made harness, with the added bonus of reflective bits. Good price too!

Totally fantastic!!

We bought this for our Old English Sheepdog, who previously hated wearing his harness - He now can't wait to get this one on! It is so comfortable for him, supports him exactly where it needs to and is so simple to put on and off. The harness inspires confidence - feels robust and wear resistant. The Velcro tags on the side can be removed and we purchased stick on lights for it, which are great for the winter! The slot for a small torch is also very handy.\n\nOverall, it's great!

Brilliant

I bought one of these for my Labrador. It is a great harness, easy to get on and off of him. It is very sturdy and well worth the money.

Brilliant!!

Wow I love this harness!! I've been after one for a while but didn't want to keep paying out so waited til my pup was almost grown. I have a 9 month old big strong English bulldog, he's a puller, gets a scent and he's off, the amount of times his other harness' have just popped off is ridiculous, but this is great! Bought with the k9 lead also, hardly any pulling, fits great, he's comfortable in it and looks lovely on. Delivered really fast too.

Harness

Thought this a great harness well made dog loves it does not like it put on his head but once fitted he is fine he also looks cool in it will buy another for my other female Husky.

Didn't help very disappointed

Was really hopeful with this harness as it had such good reviews, but didn't help at all, if anything made it worse.\nIt's fits nicely and looks well made, but it's doesn't help with pulling at all, and as the lead clips to the middle of the body it makes the dogs position awkward so difficult to control as their head is ahead of you rather than the head being at your side.\n\nI have a very energetic dalmatian who is enthusiastic on the lead, i have tried halti's, other head collars and harnesses and check chains and now this.\n\nThe best is a padded head collar, doesn't rub, stops the pulling, ability to steer and control the dog, the only downside is that the dog tries to get it off.

Smart and comfortable. Looks fantastic

When this arrived I was concerned I had ordered a size to small - size zero, however once on the fit is perfect. We have a Staffordshire bull terrier and struggled to find a nice looking harness that was comfortable and worked with the dog rather than either being too bulky , to aggressive looking or to restrictive on her chest and back muscles, or which did not cause friction rubs under her armpits. We are so pleased with this harness! It is a lot less bulky than I would of expected, the ease of use with no stepping into the harness is fantastic and so much better for our dog who disliked other harnesses for that reason. It is well made and really does seem like it will last a long while. It sits on her back so comfortably and no digging in like other webbing harnesses. The chest strap sits well and no armpit rubbing or restriction. The edging on the webbing straps is not rough or sharp and I am confident that this harness will be a favourite with her. I have already thrown out her old ones. As an owner I feel much better going out of walks with her as I am sure in the knowledge it is comfortable for her. The metal lead loop is solid and well attached. The reflective chest strap is a great feature and works extremely well.

At last!!

They've brought out a new design at last! I bought it straightaway, and also got the new sticker sets. It's a perfect fit on my Sunny. This is definitely the harness for her.
