Hi there, this is my first senior pet so I'm not sure if this is normal or not. My minpin is 13 1/2 years old, has been on a raw diet for 6 years. As of the last month or so he goes outside approximately 3-4 times within an hour of waking, before bed and he gets up to go out at least 3 times during the night. He drinks slightly more water than he did before but really not a big difference that we can see. He is still happy, eating well, being his normal self with the exception of his frequent urination. He's not grumpy or depressed or anything else. My question is: is the urination thing normal for a senior small breed??
