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.

Shipping & Returns

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

1. Delivery charges

Delivery is free on all UK orders over £59.99. For orders below that value, the delivery charge is calculated and shown at checkout before you complete your purchase — you'll never be charged an amount you haven't seen first.

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 ships, we'll email you tracking information where available. You can use this to check the live delivery status directly with the carrier.

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

7. Incorrect delivery addresses

Kibble is very small

My GSD x Collie has recently been diagnosed with stage 1 kidney disease. Only given three stars because although she has taken to this food quite well, I feel she would do better with a larger sized kibble. She is quite a big dog and does struggle sometimes with the tiny biscuits, they are only 11mm which is quite a lot less than she's used to. Hill's have told me that all their kibble is the same size so she'll either have to get used to it or I'll find something else.

Miracle food

Our 12 year old whippet was diagnosed with kidney failure and this food has transformed his life. \nLiterally overnight the change in him was visible. Able to hold his bladder longer than 2 hours and not drinking copious amounts of water.

Pretty Miraculous!

Hills Kidney Care dry food transformed my 14 year old Staffie. She was drinking huge amounts of water, typical of dogs with kidney disease, and was, after blood tests, diagnosed with that at the vet. We had been feeding her a low salt, low protein good kibble, but the vet suggested we change. We chose Hills Hills Kidney Care and she perked up immediately. Now, 4 months later, she has returned from another vet checkup and has been pronounced kidney disease free! Better than we ever expected.

A product that really works.

Our dog was diagnosed with renal failure 18 months ago and we were told that his life expectancy was 6 months. We moved to a Hill's prescription diet (kibble + tinned) and our lovely Collie is still with us (aged 15 years old).\nHe doesn't like the kidney diet products as much as his former food but it has been much better for his health and general well being.\nThe delivery service from PetsZo is excellent.

Greasey small kibble dog hates it !

Greasey food , small kibble my poor 13 year old lab is struggling to eat this. He ate normal sized kibble with ease. \n \nHills you need to do larger kibble as not every dog is small. Waste of my money. Back to drawing board to find a renal food for him now

Hopefully the . That put her right

My girl has had to start this diet because of her kidneys degenerating

My dog hates it

My dog will not touch this. I am a bit annoyed that the smallest quantity I could buy is 12kg only to find my cocker will not touch it. Even well mixed with the wet food she leaves the lot. Waste of money and a problem to find something she can eat. Turns out she also has pancreatitis and Hills K/D is too high in fat.

Does the job!,

Via routine blood tests we found out that both our dogs had high creatinine levels, so the vet suggested changing their diet to a kidney protecting diet. We firstly bought the Hills Kidney diet food from the vet, but then found it MUCH cheaper at PetsZo. Within a couple of months of eating this food (they still, had some Normal treats too!) both of our dogs had reduced creatinine levels (top of normal range). \nWe have kept feeding them a mix of the dry & wet food & kept buying it at PetsZo

Prescription diet

Prescribed by the vet for my older dog who is losing kidney function. Good product which he will eat by itself but prefers a little of the wet product mixed in.\nDelivered on time by a friendly driver.

Hills KD

Just recieved my first order, certainly not my last! Fast & prompt service for a type of dog food that isnt readily accessible in normal pet shops without having to pay the extortionate prices via the vets! I would heartily recommend to anyone who is after specialist dog kibble delivered to your door.

Hills prescription K/d

Our vet recommended hills prescription k/d to us when nearly two years ago our rottie Stella was diagnosed with early renal failure. This food has been wonderful for Stella. Her condition has got better in that her levels have reduced and she is keeping so well monitoring has gone from three monthly, to six monthly to now take her for a renal check up if we are concerned. She is now 10.5 years old and looks tremendous. We often receive comments on how well she looks for an old rottie. The food is readily eaten, Stella seems to enjoy it. Pricing is always competitive and delivery excellent. All round a super product.

Canine kidney diet

Our Labrador has just been diagnosed with early renal failure. The vet sold us a small supply of Hills KD and told us to use this new food only - no treats. I found PetsZo on the web and was impressed with their prices. Better still, their delivery was very quick, even over a Bank Holiday weekend. Just hope that this new diet will extend her time with us.

In theory he wouldn't have liked it

But apparently I don't know his taste, he loves this and it's going great.

Great food, Hill's k/d

Our lovable Rottweiler Nico is 3 years old and a very young kidney patient :( With a creatine value of 587 we feared the worst. After 3 days of eating this at the vet's Nico is much better and the creatine value is down to a constant 93!! And it's tasty food too!

J
James
Not super tasty

This product is great for preserving renal function but generally not the favourite of my dogs in terms of flavour. They only eat it if I mix it with wet food.

A
Alfie
Really good

I discovered that my boxer Indy had renal failure at 6 months old and I gave her this food up until 5 years old, when she unfortunately died. This was the best product for her, and without it she wouldn't have lived as long. She liked it a lot, always enjoyed it. Very good product.
