Why does my dog smell like urine?

Overview
If your dog smells like urine, the smell is often coming from urine on the coat, trapped moisture, skin folds or an underlying hygiene issue rather than anything serious. It can also happen if your dog has been marked by another dog, rolled in something damp, or has a skin or coat problem that’s holding onto odour.
It’s worth checking a few simple things at home first, because the cause is often easy to spot once you know where to look.
Things To Check
1. Check whether the smell is strongest after toileting, exercise, bedding time or time outdoors.
2. Look at the coat around the belly, hindquarters, tail, legs and paws for dampness or yellow staining.
3. Lift the tail and check for any discharge, redness, matting or soiling near the back end.
4. Feel the coat for sticky, greasy or dirty patches that may be holding onto smell.
5. Check whether your dog has been passing urine more often, having accidents indoors or straining to wee.
6. Look for skin irritation, scabs, soreness, licking or chewing, especially if the smell seems to come from one area.
7. Consider whether your dog has been wet, muddy or recently groomed and not fully dried.
8. Notice whether the smell is new, getting worse or coming back quickly after washing.
Common Causes
The most common reason is urine trapped in the coat, especially on long hair, around the back end or on a dog that’s had an accident indoors.
Wet fur can also hold a urine-like smell, particularly if your dog has been in rain, puddles or damp bedding and hasn’t dried properly.
Another common cause is poor coat condition, matting or general dirt build-up, which can make normal smells seem much stronger.
Sometimes the smell is linked to skin irritation, a skin infection or sore areas that are being licked, which can create an unpleasant odour.
Less commonly, urinary problems can be involved, especially if your dog is having accidents, leaking urine or seems uncomfortable when passing urine.
What To Do
Start by bathing or wiping the affected area with a dog-safe approach to remove any urine, dirt or wet residue, then dry the coat thoroughly.
If the smell is coming from long hair around the back end, a careful trim or regular grooming routine may help keep the area cleaner.
Wash and dry bedding, blankets and any fabric your dog rests on, because odour can keep transferring back onto the coat.
Keep an eye on toilet habits for a few days so you can tell whether the smell is only a coat issue or seems connected to urination.
If the smell keeps coming back, note where it seems to start and whether there are any skin changes, accidents or changes in behaviour.
When To Contact A Vet
Contact your vet if the smell seems to come with frequent accidents, straining to urinate, discomfort, blood in the urine, increased drinking, or ongoing skin soreness. It’s also sensible to get advice if the odour persists despite good hygiene or your dog seems unwell.
Products That May Help
Regular washing and coat care can be useful when you’re managing a dog that’s picking up urine smells or damp odour from the coat.
