Signs your dog might have a UTI
In addition to increased frequency of urination, the classic signs of a UTI are:
Urination in inappropriate places
Difficulty when urinating (straining)
Pink or red urine (indicating the presence of blood)
Strong and/or foul smelling urine
Lethargy
Fever
If you notice any of these signs you should have your dog examined immediately. Your veterinarian will give your dog a urinalysis to determine the presence of bacteria – which will confirm that your dog has an infection. If your dog is diagnosed with a UTI, your veterinarian will probably recommend oral antibiotics to treat the infection. Treatment usually includes one to two pills a day for the duration of at least two weeks.
Steps you can take to prevent UTIs
Make sure your dog has the opportunity to go outside every few hours in order for him to relieve himself. Also, ensure your dog drinks plenty of fresh water throughout the day. This will help flush out his urethra and help prevent bacteria from entering his bladder.
