Is your dog urinating more often or is it larger amounts when going?
any changes in eating/drinking habits?
Thanks for replying.
This is often due to a urinary tract infection. The bacteria causes inflammation in the bladder, which triggers a signal to the brain that the dog needs to urinate with a full bladder, even though technically the bladder has not had enough time to fill up.
A urinary tract infection can often easily be treated with a round of antibiotics, but it is not something to put off treating for too long, as it is very uncomfortable for the dog and can eventually lead to either kidney infections or chronic cystitis.
Your vet will want to check a fresh urine sample to determine which type of bacteria is causing this and if crystals or casts are present, then choose the proper antibiotic for curing. Until then, encourage plenty of fresh water intake to help cut back on irritation.
Best of luck, and let me know if I can help further.
