Why is my dog drinking and peeing excessively after diarrhea?

Thanks for using Petco Pet Education Center, formerly Petcoach. The increased drinking and urinating could result from residual infection, and irritation to the bladder during surgery. The diarrhea can be due to stress, pain, or the antibiotics. All in all I would say that if she is eating and becoming more active, I would not panic yet. Give it a few more days. If no improvement in the urination problem in 2 days, or if worsening in any way, it’s time for a recheck with your vet. Best wishes to you and Chanel.

I would have Bella seen by a vet immediately. She could be suffering from a pyometra, which would cause her to be lethargic, shiver from pain, have the brownish discharge, and drink and urinate a lot. A pyometra is fatal without treatment, so she should be seen by a vet now. A UTI or bladder stones are other differentials for her symptoms, but the risk is of a pyometra is high. The vet can do a physical exam, blood tests, urinalysis, and x-rays to diagnose what is causing her symptoms so she can be treated. If she does have a pyometra, spaying her is part of the recommended treatment. Please take her into a vet now.

Increased thirst and water consumption can be seen with a pyometra from the bacteria that are present in the uterus, but it would be a little unusual for these symptoms to continue one week after surgery. It might be a good idea to have Murlee rechecked by your vet - they might want to check blood work to make sure her kidneys are functioning okay since kidney disease can also occur secondary to a pyometra.

Thank you for submitting your question Sophie. I recommend that she sees her veterinarian for blood and urine testing. The signs you have described are most common with diabetes. They can also be seen with kidney disease, liver problems or an adrenal gland disorder. I hope this information helps!

The most common diseases that cause dogs to drink and urinate more are urinary tract infections, kidney disease, liver disease, diabetes, cushings disease, and addisons disease. If the urinalysis was negative for infection then, hopefully, the bloodwork will help diagnose the problem. Hopefully, the bloodwork will be back in the morning. Hope she feels better soon!

Excessive water consumption, weight loss despite still eating can signal diabetes. If she is nursing puppies, that is the most likely cause for her weight loss. The blood is concerning, it could be anything from parasites, to a viral or bacterial infection, just to name a couple of possibilities. I recommend getting her in to see your vet right away for an exam and labwork. Also, while she is nursing puppies, she should have access to lots of fresh water and as much high calorie puppy food as she wants at all times.

I would recommend having your dog seen as soon as possible if her symptoms are not improving tomorrow, even if this means taking her in to another vet or an emergency vet. Diseases we worry about with these symptoms include Cushings Disease (where the adrenal glands produce too much steroids), diabetes, kidney disease and liver disease. Some of these conditions can worsen quickly and become life threatening so having her examined and having bloodwork and urinalysis done as soon as possible to determine the underlying cause is the safest way to proceed.
