Wow that’s a lot of abnormal symptoms without the vet resolving any. Seems like they are guessing and giving possibly unneeded medications since it never resolved the problems. No definitive diagnosis of hypothyroidism but put on that medication could cause more symptoms .
Has the vet given a cause of the constant UTI’s? Were these her symptoms?
( The most common cause of UTIs in dogs is bacteria, which enters upwards through the urethral opening. The bacteria can develop when feces or debris enter the area, or if your dog’s immune system is weakened from lack of nutrients.
In most cases, E. coli is the bacterium that causes such infections. In more severe, but less common cases, causes include cancer, bladder disease, kidney disease and stones, diabetes, bladder inflammation or infection, spinal cord abnormalities, and prostate disease.)
Symptoms of UTIs in Dogs
Bloody and/or cloudy urine
Straining or whimpering during urination
Accidents in the house
Wanting to be let outside more frequently
Dribbling urine
Licking around urinary opening
Fever
If not then is it possible she never had constant UTI’s? Because if she did they at least should have found a cause and preventive treatment.
Also is it possible she has chronic pancreatitis? Then a change in dog food and given high protein and low fat diet should help. But worst thing is the constant switching of food . This will give stomach pain and diarrhea . Any switch has to be done VERY VERY VERY slowly to get used to. With the chicken was it ONLY white meat? Normally if a dog has pancreatitis they can tolerate WHITE meat boiled chicken (not from store bought seasoned already) and plain rice. Give this for a few days and a few times a day and see if she tolerated that. Give a break from meds and all the switching of foods and just work on her digestion first possibly. Have a calm place for her to eat with no excitement so the food doesn’t go right through her if she’s an anxious by nature dog. Hope this helps a little If not take her back to vet for some definitive tests and answers.
