Why is my dog vomiting, not eating, straining to pee after AZO?

An immediate check up at your local veterinarian is required as this drug could cause toxic side effects. The signs you are describing are compatible with urinary tract infection/inflammation and Piper should be investigated and treated for it, starting from urine analysis and possibly an ultrasound of the bladder. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

As far as I know this is a rare intoxication in dogs (it has been reported though). It can cause hepatotoxicity and rhabdomyolysis secondary to phenazopyridine toxicity in a dog. Signs described are shifting leg lameness involving all 4 limbs, progressive reluctance to walk and severe diffuse muscle hyperesthesia (pain). I would recommend to take her to your veterinarian for a check up. Blood tests may be required to check possible liver damage and function.

One pill shouldn't alter the results, so that will be fine. AZP should not be given to dogs, it's not a medication that can be safely used in this species. The best way to prevent infections is to make sure Amelia drinks lots of water, and you take her out to urinate frequently. The longer she holds her bladder, the more chance bacteria has to build up in the bladder leading to infections.

Azo tablets have been show to potentially cause methemoglobulinemia in dogs and cats and should not be given. It also can cause a dry eye condition in dogs. I would recommend not giving this to Eve. There are pet formulated cranberry tablets that you can purchase from your veterinarian (if available) or through your local pet store.

This behavior is very common with UTI, but could also be caused by urinary bladder stones, kidney disease, and a few other things. I would recommend that you have Ruby examined by a vet. A urinalysis and x-rays of the bladder to check for stones are the first step.

Any medication can cause nausea and vomiting in individual patients and both urinax and antibiotics could be contributing. If the discomfort and straining has resolved you should discuss withdrawing the urimax with your vet. It would be useful to know how long she has been on the antibiotics - I would recommend a repeat urine sample if longer than 5-7days to see if the condition has cleared and it may be possible to withdraw the medication to see if this resolves the vomiting. If so, a repeat sample after 7-10days would be recommended to check for any relapse given the short treatment time.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Zeus. I am concerned about a urinary obstruction by a urinary stone or a urinary tract infection with resultant inflammation/straining/and urge incontinence. If he cannot pass a good stream of urine when urinating you need to have him evaluated immediately to determine what the problem is. If his bladder pressure increases, the bladder to can stretch out and will lose some of it's muscle contraction. The pressure can also back up into the kidneys causing kidney damage and failure. Again if he can't urinate a good stream, is straining a lot, you need to get him evaluated right now to prevent further problems. None of the meds he is on should be causing this. He is neutered so an enlarged prostate isn't possible. Good luck with Zeus. I hope he feels better soon.
