Causes of dogs suddenly urinating blood:

1. In estrus. When a male dog is in estrus, it may cause traumatic bleeding due to its violent movements, and genital infections may also cause such symptoms. Female dogs may also have blood in their urine due to their menstrual period being mixed into their urine.

2. Food poisoning. If dogs accidentally eat onions, garlic, scallions, grapes, chocolate and other foods, the disulfides contained in them will destroy the red blood cells in the body, resulting in hematuria.

3. Urinary system problems. If your dog has symptoms of frequent urination, painful urination, or blood in his urine, it may be a urinary tract infection that requires timely anti-inflammation.

Treatment methods for dog blood in urine:

1. Take medicine. If inflammation causes blood in the dog's urine, you can give the dog Qianbeimikang beef tablets + Sunuo/Amoxicillin.

2. Pay attention to your diet. Usually, you should avoid foods such as onions and garlic for dogs to prevent them from being poisoned. Try not to feed dogs food that humans eat. The reason why dogs are not allowed to eat it is because there are many condiments and heavy salt content. Long-term consumption may easily cause damage to the dog's kidney function.

3. Clean up. If the dog is in estrus, it will cause false blood in urine. Clean the dog properly and it will become normal after the estrus period is over.
