Hello. My Dog Has Reently Started To Urinate Anywhere In

hello. my dog has reently started to urinate anywhere in the house. He urines on my bed, pillows, on the sofa and carpet. It doesn't appear he is able to hold his urine if he is full. He also raises his legs outside and stands for a very long time trying to pee but nothing seems to be coming out. Usually he raises his legs, pees and then run along. Can you tell me if this is a medical condition such as an UTI?
