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

Last updated: 16 August 2026

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.

2. Order processing and dispatch

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.

Time in transit after dispatch depends on the delivery method selected at checkout and your location. Total time to receive your order is therefore the dispatch window above plus the carrier's transit time.

5. Tracking your order

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

Please check your delivery address carefully at checkout. If you spot a mistake, contact us immediately — we can usually correct it before dispatch. Once an order has shipped to an address you provided, we may not be able to recover it.

Quality that the dog enjoys

My dog has repeatedly suffered from painful stomach inflammations. Since we switched to this food, the problems are "sorted". He enjoys it, and he's genuinely much fitter and livelier. \n,The food also contains an active ingredient that prevents diarrhoea.

Perfect!

Super experience with the food! My dog tolerates it really well, her digestion is great, and she obviously enjoys the taste too 😊 \n\n,For us, the best food!

Diarrhoea

It really helped our Golden Retriever female. I’m now continuing to mix it with regular dry food. 👍👍👍

From diarrhoea to vomiting

Unfortunately, our senior dog has often struggled with diarrhoea. After ruling out organic causes, we were given this food by the vet, who swears by it. Despite a slow transition, our dog kept vomiting repeatedly, and there were more problems than before. We might give it another try, as it’s possible he coincidentally had a gastrointestinal infection right during the food change, but I fear he doesn’t tolerate it. Best regards and good luck to all those with sensitive pets!

Gets eaten well and the output is good too.

The only dry food our dog can tolerate

It tastes good, helps, and after almost a year of searching, it's the only (dry) food our dog can tolerate. No more diarrhoea and no more vomiting. The dog eats with such enthusiasm, it's a joy to see. \n,I'm very, very glad to have had this food recommended to me. Interestingly, he tolerates it despite his intolerance to chicken!

Helps with problems related to the anal glands

My senior dog has a sensitive stomach and digestive issues, which ultimately led to inflamed anal glands. This food really helps to get these problems under control again and is well received.

More than satisfied

Due to my dog's chronically irritated bowel, we had to visit the vet regularly every 2-3 weeks (bloody diarrhoea, bloody vomiting, loss of appetite). Our vet gave us this food back then to try it out, as my dog is also very picky. He really enjoys eating this food, and we haven’t been to the vet for 8 months now, thanks to this food!\n\n,The ingredients in the food aren’t the best, but it helps my dog a lot, and he likes eating it.

Helps with stomach and intestinal problems

My dog used to have recurring stomach and intestinal issues and soft stools. Ever since she started eating this food, her output has been perfect. So it seems to help. Plus, she enjoys eating it, even though she’s picky. The composition is admittedly questionable, but since it works, I’ll keep feeding it to her for now.

Hill's Gastrointestinal Biome

Our royal poodle has always suffered from digestive issues, even though he is very young. After his pancreas levels dropped significantly and the diarrhoea wouldn’t stop, we switched to Hill's Biome. The result was astonishing: no more diarrhoea within 6 hours. He loves eating it, it helps him stay healthy, and he’s gaining weight again. Whether it’s the highest quality food or not doesn’t matter to me anymore, because he couldn’t tolerate the expensive food, no matter the brand or price.

Top feed

After elevated pancreas levels (diarrhoea, nausea, and vomiting), I switched to Hills food on the advice of my vet following a blood test. The composition, as far as a layperson can tell, is so-so. But the results regarding stool and pancreas levels after two weeks of consistent therapy were excellent. This food is absolutely brilliant for gastrointestinal issues. After two weeks, a follow-up blood test showed the pancreas levels were very good. As the saying goes, "Gut with charm." I'll definitely use it again at the slightest sign of trouble.

Great service

I have been using this product from my vet for a few weeks now as my dog has a super sensitive tummy.\n\nI ordered on a Wednesday and it arrived on Thursday so great service will definitely order again especially as its 50% cheaper than my vets prescription

Hill's Prescription Diet Canine Gastrointestinal Biome

The food was recommended to me by my vet for my dog (4 years old). My dog took to the food straight away and absolutely loves eating it. (Previously, he was on wet food.) Since Rover started eating this food, he’s back to eating normally, his digestion is great, he’s fit again, and he no longer has diarrhoea!

Sorted our Norfolk Terrier's diarrhoea in 2 meals

Our 4 year old dog, Milly, was suffering from terrible diarrhoea and having failed with our usual solution of a chicken/rice mix the vet prescribed this biscuit. Milly loves the biscuit and she rapidly recovered from her debilitating state. Relieved and happy, thoroughly recommended.

Excellent

Hi,\nvet here. I was recommending this prescription diet to many of my clients, but recently had test it on my 7kg mix breed and 25kg Belgian Shephard dogs. They both found this food very yummy and more importantly it settled their diarrhoea within 24hrs.

Dmitriy Mukhtarov
small pellets no warning

Dogs don't like it maybe because the size of pellets will suit a small, bag style dog only. The package shows a border collie, but GSD / medium/large size breeds would suffer. not recommended unless your dog is really small.

Hills Gastrointestinal Biome Digestive/Fibre Care

A really good food, my senior dog (13 years old) had giardia and terrible diarrhoea, and this helped so quickly. Within 2-3 days the stool consistency was better. We continued using it after worm treatment. The gut slowly repaired and after about 2 months he was completely better.\nTOP dog food that I completely recommend!!

A really good dog food, it helped my old dog (13 years), who had contracted giardia and had terrible diarrhoea, very, very quickly. \n,Within 2-3 days, her stools improved. \n,We continued giving it to her for a long time after the deworming treatment. Her gut slowly recovered, and after 2 months, she was doing really well again. \n,TOP dog food – I can only highly recommend it!
