what symptoms has the dog got?
Its pretty much the same as humans. Needing to wee a lot and its painful to wee, maybe blood in wee, fever and shivering and dog looks ill.
Frequent weeing, often somewhere inappropriate like indoors or on your bed. Cranberry tablets can help if its cystitis, or if its a spayed bitch the vet can give you tablets.
She had strong smell of urine on her and wet in house doesn't eat all her food not like her so had to the vets blood test came back ok could not get a urine sample vet said she's a bit tender underneath so looks like infection on antibiotics so fingers crossed
