Giardia Infections In Pet Shop Puppies

Updated September 19, 2021

Are you thinking of getting a puppy from a pet shop?

Or do you wonder if it’s OK to buy a puppy from a pet shop.

Or does your pet store puppy have the any of following symptoms?

  • Droppings that aren’t 100% solid
  • Difficult or slow toilet training
  • A fussy or picky appetite
  • Poor weight and slow growth

Then you need to read this.

The Problem With Pet Stores

Modern pet stores look upmarket, have stylish branding and do everything they can to give the impression of a responsible place to buy puppies. Some even possibly are. The public can only judge them at their words, and I’ll never blame anyone who does.

However, the reality is often different.

Here an edit of the third message I sent to a local shop called Boutique Paws. I’ve added headings and images to make it easier to read. It’s important to stress that the shop is not the only one of its type and buyers should beware of all similar stores, no matter how well polished the exterior.

Dear <pet shop owner>

It is with disappointment that I have to report the latest case of a sick puppy sold via Boutique Paws. I am hoping this time it will be received with a commitment to investigate the illnesses I have seen in puppies from your store. 

Giardia In Puppies

intestinal giardia trophozoite

As you can probably guess by now, the problem concerns multiple giardia infections. Giardia is a single-celled protozoan parasite that causes gastrointestinal signs such as vomiting, diarrhoea, weight loss and even death in puppies. If that it not enough, it is also a serious human health risk, especially to children in contact with these puppies.

The latest incident concerns a just-purchased puppy who was taken to an emergency vet after passing blood. I subsequently examined the pup and found him to be significantly underweight, and infected with giardia. He has been started on treatment, and I expect him to make a full recovery. However, it never should have happened.

More than this single case, the scale of the situation is frankly alarming. I am just one of hundreds of vets in Adelaide, yet I have seen three puppies from your store recently with giardia. Most of the time, these infected puppies show only mild persistent diarrhoea and poor growth. Unless a vet already suspects giardia, it is likely that this will be put down to ‘change of diet’ (as did the emergency vet) and the subsequent slow toilet training as just ‘one of those things’.

My history dealing with puppy farms is the reason I can see the problem clearly, but I fear not all vets share my bitter experiences. If puppies with giardia are not identified via specific testing, they will carry and pass on the parasite for life. Who knows how many are affected.

Where Giardia Comes From

I hear you have been telling customers who complain that the puppies are getting giardia from their water or environment. If that is so you need to be able to explain two things:

  1. Why I almost never see giardia in puppies from any other source except yours
  2. How all three puppies could have picked it up in those few days despite having loose stools from day one

There is strong circumstantial evidence that you are unwittingly selling puppies with giardia. You are welcome to prove me wrong, but to do so you need to stop being in denial. The only way forward is to get veterinary advice.

Giardia is a parasite of dogs that is easily eliminated and controlled with good hygiene, husbandry and veterinary care. Persistent infection in pet shop puppies can only mean one of two things:

  1. Breeders sending out puppies infected with giardia
  2. Puppies being infected wth giardia in the shop

Either way, this is unacceptable. If on one hand you are purchasing puppies from such disreputable sources, you need to re-examine why you are in the business in the first place. Your responsibility is to refuse to deal with them until they get their house in order. The presence of giardia indicates deficient or absent veterinary care.

If on the other hand, puppies are being infected in your shop, it is a failure of basic hygiene, and you need to get local veterinary advice. My personal opinion is that the answer is likely to be a combination of both factors.

Giardia has to come from somewhere initially, but the fact that all types of puppies appear to be infected suggests further spread is occurring.

How To Prevent Giardia In Dogs

Fixing the problem is certainly not just about dispensing antibiotics. It will involve all of the following steps:

  1. Testing puppies on arrival to determine the source of the problem
  2. Refusing to deal with the breeder(s) who return positive test results
  3. Using pens for puppies that can be easily disinfected
  4. Never mixing puppies from different sources or with differing ages
  5. Testing existing pets and breeding animals owned by the shop
  6. Periodic ongoing monitoring

Of this list, only hygienic pens are difficult, but that’s the price we all pay for housing animals properly. You are very welcome to come and learn how we did it in our new clinic. However, I suspect your main problem will be point 2.

Where Pet Shops Get Their Puppies

From previous discussions, I know that you (like most pet shops) struggle to find enough locally-bred puppies to sell. Therefore you are forced to use commercial large scale breeders mostly based in Victoria.

I can’t say that these breeders are the source, but this will be easy to check with a cheap test. If they are, you must stop using them until they commit to a solution. Selling fewer puppies may be the price you have to pay for selling puppies with fewer problems. 

It will shock you to learn that puppies from Boutique Paws are indistinguishable to me from the puppy farm puppies I used to see. I am sure this was not your intention in setting up the shop, and I hope this fact spurs you into action. You are putting the health of puppies and their families at risk, but you are also only a step away from the RSPCA becoming involved. 

Kind Regards, Dr Andrew Spanner, Walkerville Vet

Addendum: I published this due to the lack of an adequate response to my previous attempts to help and offered the owner a right of reply. Since then, an outpouring of stories of problems posted on our email (which I sadly felt were too risky for me to leave there without verification) has made me withdraw the offer.

The situation appears a lot more serious and widespread than even I feared. Puppies are being diagnosed with giardia across Adelaide. The day after I posted this I saw a fourth, and I expect more to come.

Update 15 July, 2019. This post was published 7 days ago, and the shop was temporarily closed shortly afterwards. Boutique Paws announced today that they are working with the support of Pet Doctor Woodville. With attention to the points outlined above, there is every reason to believe that puppies can be sold free of infection. I wish them the best.

However, the two puppies from BP that we have tested since that date have both been carrying giardia infections, one with no obvious symptoms. Therefore, it’s a good idea to ask for a test just to be sure.

Please note that it is never normal for puppies to pass blood in their poo, and the routine use of antibiotics in puppies may only be masking illness or encouraging the development of antibiotic resistance.

What To Do Next

To those reading this, I hope what I’ve written helps you to either choose a puppy or help the one you’ve got. If you know someone who’s purchased a puppy from a pet store recently, not just Boutique Paws, send them this link. The rates of infection are so high that there’s a good chance their puppy is infected too.

If you have a puppy with some of the symptoms I mentioned, please talk to your vet for a non-judgemental and thorough consultation. Nobody wants to live with giardia. My dogs have never had a loose stool in their life and neither should yours.

Lastly, it’s not your fault to trust what you’ve been told. It even took me a while to see the problem. I would only ask that in tackling it we don’t expose the shop staff to any stress or criticism.

So where can you get a good puppy? Follow this link.

Note: comments from owners of affected puppies are very welcome. They will be published anonymously but in the interests of complete accuracy I will contact you privately to get consent to talk to your vets. They will be happy to assist.

    1. Wow unbelievable thankyou forwhat you hav done
      I myself just bought a puppy from fairfield markets in sydney called anthonys pets it my puppy has gardia and also coxcidia and waiti g on one more test he as soso sick picking up now im just so glad i saved him
      These people need to be dealt with severely

  1. Bought a spoodles from boutique paws 2 half weeks ago gorgeous thing but has been a nightmare — having three grandchildren too look after —- while mum working . So took her to nearest vet East side vet and with sample diagnosed with giardia . I’m furious—- rang RSPCA EXPLAINED all details which they said they will follow up in the mean time l have another dog which l thought ld better follow up with sample —NOW GARDIA!!
    PLEASE SOME ONE OF AUTHORITY check this shop as there is going to be not only puppies sick BUT CHILDREN after Christmas!!!

  2. [Two sentences removed until can be verified]. A sick smelly dog is not fun let alone the expense of new bedding and trying to white king everything.

    1. Sorry to hear Margaret. I first brought the giardia problem to the shop owner’s attention in May 2019, but it’s possible other vets had done so sooner.

  3. You have my great respect and admiration for bringing this matter to public attention using such reasoned argument in such a polite manner.

    I must admit I was astonished to learn that SA law still permits both puppy farming and the sale of puppies and kittens in pet shops as in Victoria this was prohibited by the Puppy Farms & Pet Shops Act of 2018. If pet stores wish to sell puppies and kittens they are now required to liaise with animal shelters to re-home animals.

  4. Thank you for taking this issue to the public. We brought our “Moodle” from Boutique Paws 2 years ago. We were told he was 12 weeks old. We took him home with diarrhea, persistent weeing (urine infection) and not eating. After two days of not eating I rang the owner and he said boil some chicken & rice. I took him to vet on the Monday to be told our puppy was only 6 weeks old and had no teeth. We were concerned that we had been sold a puppy farm dog and wanted evidence of the parents. We were sent photos of a poodle & Maltese terrier. We then attended puppy preschool to find out that the owner was unsure if our puppy was born 3/3 or 6/3 as there were two litters at the same time. Obviously this made us skeptical of who were the actual parents of our “expensive” mixed breed dog. I expressed my concerns to be told to bring him back for a refund. Not something you can do when you have children who have grown to love your puppy after a week together!! Anyway we do love our quirky looking dog very much and we call him our rescue dog. He is very anxious, itches incessantly and wees on everything. Never ever again would we buy from Boutique Paws. Our new second puppy from a breeder came with teeth and was toilet trained. It made the early puppy days a breeze.

  5. Hi my husband and i are looking for a Labrador , female, between 1-4 years of age, a rescue dog or one that needs a new home for whatever reason.

  6. Thankyou Andrew for having the guts to take a stand. Sometimes it only takes one person to activate more people that might not have been confident enough to do something,

  7. Thank you for having the strength to bring this issue to the public, there are so many heartbroken puppy owners who have purchased “expensive” puppies in good faith, only to have them die in a lot of cases due to ignorance or lack of finances to get veterinary care early enough.

    Thank you.

    1. Seems a bit harsh to act as though the pet shops don’t give a crap
      They clearly do as you can’t be involved with puppies as they are and not get invested
      My puppy that I bought was fussy and did have a few settling in issues but the vet care I had and support over the phone was amazing
      Bought to the attention of the business owners now let them take the advice and rectify the issues
      You need to have GOOD pet shops to help you find the right puppy so you don’t buy a pup then hand it to the rspca once it’s an adult.

      1. Hi . Interesting article. What is the steps one takes in getting rid of giardia in dogs once diagnosed- if you unwittingly purchase a pet with giardia? . If you have more then one dog in the household what would your recommendations be and cost +_ per a dog to rectify?

        Thank you

      2. Hi Brad. It starts with a trip to the vet. There are multiple drugs that can be used, combined with environmental decontamination at the same time. The cost will depend on how quickly the giardia is resolved and how much resistance has already developed in the bug (which my in my view seems to be related to whether either the breeders of the pet shop have had access to drugs in the past, as this makes it worse).
