Buster is in the wars lately with tumours and allergies and now I think he may have another issue. Buster is taking forever to have a wee. Every now and then over the last couple of months (has happened about 4 times) Buster will take about 5-10 mins to have a pee. I've watched him and there is urine coming out, albeit sometimes slowly. This morning I let him out and he took about 10 mins to have a pee. I let him back in and gave him his breakfast, then went to let him into the living room and he stood there and started peeing! Also last week the OH came to bed and was checking on the dogs and noticed buster had urinated in his crate. These two times are the only times Buster has ever urinated in the house in the two years that I have had him. Buster is 3 years old, male and is a giant breed. So peeps what are your thoughts? Did you think this is normal?
