A urinary tract infection is uncomfortable for a dog, and because they can't tell us their bits are sore, it usually shows up as a change in their toilet habits. If your dog has suddenly started asking to go out constantly, straining, or having accidents indoors when they never used to, a UTI is one of the things a vet will want to rule out. The short answer: watch for changes in how, how often and how comfortably your dog wees, and get these signs checked promptly, because a UTI needs proper veterinary diagnosis and treatment, not home remedies.
What is a UTI in dogs?
A urinary tract infection is an infection somewhere in the urinary system, most often the bladder. It makes weeing uncomfortable and can make a dog feel the urge to go far more often, even when there's very little to pass. UTIs are more common in female dogs but can affect any dog, and they're something dogs of any age can develop.
While grooming isn't about diagnosing this, we're often the ones who spot when a dog seems uncomfortable, unusually keen to wee, or off in themselves, and a quiet word with the owner can prompt a helpful vet visit.
Signs of a UTI to look for
The signs tend to centre on your dog's toileting. Look out for:
- Weeing more often than usual, or constantly asking to go out
- Straining to wee, or producing only small amounts each time
- Accidents indoors from a dog who is normally clean
- Blood in the urine, or urine that looks cloudy or smells strong
- Licking at their private parts more than usual
- Signs of discomfort when weeing, such as whimpering or an anxious posture
- Drinking more than normal in some cases
A dog with a UTI may otherwise seem fairly well, or may be a bit subdued. Any of these changes, especially blood in the urine or obvious straining, is worth a vet call.
Worth knowing: Straining that produces little or no urine can occasionally signal a blockage rather than a simple infection, particularly in male dogs. That's an emergency, so if your dog is trying to wee repeatedly and nothing is coming, ring your vet straight away.
When to see the vet
The honest answer is: promptly, and always. UTI-type signs shouldn't be left to see if they clear up on their own. Contact your vet if you notice frequent weeing, straining, accidents, discomfort or any blood in the urine.
There are two reasons to move quickly. First, an untreated infection is genuinely uncomfortable and can spread upward toward the kidneys. Second, the same signs can point to other issues, such as bladder stones, crystals or, in male dogs, a blockage, so a vet needs to work out what's actually going on. They'll usually test a urine sample to confirm. For a reliable, vet-written overview of dog health conditions, the PDSA Pet Health Hub is a good place to read up before your appointment, and Dogs Trust has general health guidance too.
If you can, take a fresh urine sample with you (a clean container slid under your dog as they wee first thing works well). It saves time and often speeds up the diagnosis.
Please don't try to self-treat
I'll be very clear here, because it matters. A UTI needs proper veterinary diagnosis, and often prescription treatment, to clear it safely. Please don't reach for human medicines, leftover tablets from a previous problem, or unproven home remedies from the internet. Some human medicines are toxic to dogs, wrong doses are dangerous, and masking the signs can delay finding the real cause.
Cranberry supplements and the like are sometimes suggested, but they are not a substitute for a vet assessing your dog, and giving anything without veterinary advice risks doing more harm than good. The safe path is simple: notice the signs, see your vet, follow their plan, and finish any prescribed course exactly as directed even if your dog seems better sooner.
Frequently asked questions
What are the first signs of a UTI in dogs?
Usually a change in toileting: weeing more often, straining, producing small amounts, accidents indoors, or licking at the area more than usual. Blood in the urine or an unusual smell are also common early clues.
Can a dog UTI clear up on its own?
It's not safe to assume so. UTI signs should be checked by a vet promptly, both to treat the infection before it spreads and to rule out other causes like stones or a blockage.
Is straining to wee an emergency?
It can be. Repeated straining with little or no urine coming out, especially in a male dog, may indicate a blockage, which is a genuine emergency. Ring your vet straight away.
Can I treat my dog's UTI at home?
No. Please don't use human medicines or home remedies. A UTI needs veterinary diagnosis and often prescription treatment; self-treating risks harm and can hide the real problem.
