My dog is a Giant German Rottweiller, he is 5.5 years old and he weighs 185 pounds. Lately, for the last 3 weeks or so, he has been drinking a lot and urinating much more frequently. So much more that he cannot hold it through the night. This dog has been able to hold his urine like a champion for the last 5 years, but lately, it has gotten to where he has to empty an over-full bladder ever 2-4 hours without drinking much water. Waht could be some causes for this? I don't think it is behavioral as he is always in good spirits and he is ultra-ashamed every time he has an accident in the house. I would appreciate any advice that you could give as well as any possible causes for this condition.
Your pet need to be seen by a vet. Some common diseases that cause dogs to drink and urinate more are diabetes and kidney disease. I recommend a blood test. Good luck, vetcare
