I’m going through the exact same thing at the moment. I adopted a puppy from a breeder in mid-December, but unlike you, the first symptoms appeared as soon as I got him home—blood in his stools that very evening. I phoned the breeder who told me it was just down to stress, which sounded plausible. However, I waited three days and it didn’t clear up. Plus, the stools were very specific: mucousy, soft, frequent, and bloody. I did some research the night before my vet appointment, and everything pointed towards Giardia.
The vet agreed and started a 3-day course of Panacur. Everything seemed better then—his stools were formed again, no more blood, and most importantly, the puppy finally started eating, as he’d been off his food before.
The joy was short-lived though. 24 hours after finishing the treatment, the symptoms came back with a vengeance. I took a stool sample in for testing and the result came back: Giardia. We did another 10 days of Panacur, but this time there was no improvement at all during the treatment.
So, to pick up where I left off, 10 days later (which was a week ago), we switched to Metrobactin, because the only thing really effective against Giardia is Metronidazole (antibiotics like Flagyl or Metrobactin). For five days, everything was great—he got his appetite back, his poos were less frequent and better formed... basically, a huge relief. Then tonight, 48 hours after finishing the first round of Metrobactin, the diarrhoea and blood are back...
I should mention that I’ve followed every bit of advice you can find to the letter: steam-cleaning the house every day, using quaternary ammonium disinfectants, changing his bedding daily, washing our own clothes with disinfectant (like Dettol or laundry cleanser), bathing the dog with Douxo (an ammonium-based dog shampoo), wiping his bum after every poo, putting a fence up on the patio so he only goes there, and then picking it up and scrubbing the spot with boiling water from the kettle... same for his bowls. Honestly, as someone mentioned before, I’ve become a total obsessive clean-freak and it still hasn't worked; it’s come back. So no matter how many precautions you take, it seems these parasites are incredibly hardy.
After becoming something of an expert on Giardia from reading so many papers and testimonials, you basically have a few options:
- Keep going with the treatment and after a few months it will eventually clear up, but in the meantime, you need to stay mentally strong to cope with it all—and have a healthy bank balance to afford the products.
- Change his diet. Most kibble contains grains and therefore carbs, but check with your vet first as our puppies' gut flora isn't in the best shape right now.
- Supplement with grapefruit seed extract between treatments, as some people do. Apparently, it can be quite effective and it’s a good natural support that won't mess up your dog’s system like the meds do.
All of this while continuing with the manic cleaning at home, obviously, otherwise it’s no fun...
- The final option: return the dog to the breeder. But that’s so hard, especially when you’re already attached to the little guy. I’ll admit my partner is leaning towards this because we aren’t sleeping anymore and we’re terrified of him passing the parasite—which is a zoonosis—to our 3-year-old.
Regarding the cleaning, if it helps, standard supermarket disinfectants often aren't strong enough. You’re better off getting something like Safe4 or Virkon (but if you have kids, only clean when they aren't around and keep the place well-ventilated). You can also look for heavy-duty kennel disinfectants or brands like Zoflora which contain the right active ingredients. Other than that, use steam and boiling water wherever you can.
As for the "last resort" of returning the dog (because let’s face it, this illness is definitely not compatible with a busy, complex job)—if you took steps early on to detect the Giardia with tests and everything, the only legal route is "misrepresentation." Basically, arguing that you wouldn't have taken the dog had you known about the condition. That’s my situation, and probably the case for others who are having nightmares over this.
Anyway, all this to say you aren’t alone. It’s just that this parasite must be super resistant to treatment...

Thanks for the cleaning tips! I didn't realise some of those disinfectants were less effective—frankly, given the price, I wish I'd known sooner! It’s a total money pit... The worst part is I actually work at the supermarket and I'm only just finding out that the own-brand stuff is better value... and I've been using that brand specifically! I thought I was doing the right thing by buying the expensive "name brands"...
So, I’m going to give that a go.
In my case, giving the dog back is out of the question for two reasons: firstly, he didn't catch it at the breeder's, and secondly, I’m so incredibly attached to him!! He’s my best four-legged mate.
But I can understand your situation, because he really should have been healthy leaving the breeder, or at the very least you should have been warned.
If I’d known about this illness, though, I definitely would have thought twice before getting a dog... I knew I needed a budget for him, but I hadn't planned for this kind of disease that I’d never even heard of!
I have an 8-year-old child who is quite fragile, so I completely understand the fear of them catching it. But actually, from what I’ve read, it’s quite rare to catch it from a dog; it’s usually passed human-to-human (Giardia in dogs vs. giardiasis in humans), if I’m not mistaken. You’d really have to not wash your hands etc. for it to happen. Basically, if you have a basic level of hygiene, it’ll be fine. But I get that with a 3-year-old who likes crawling around on the floor, it’s not easy.
Best of luck to you. We are on the final treatment—15 days this time (Panacur + Metrobactin). Symptoms: stools are formed but very soft, and above all, incredibly smelly. Today is day 5.
Oh, and to top it all off, my washing machine has broken down, so that’s another £10 a week at the launderette...
