We have a nearly 5 month old Wheaten Terrier. We have not used a crate and so he is closely supervised at all times. When he's calm and resting, he can go 2-3 hours sometimes without needing to go out but, whenever he's playing, or gets overly excited and especially between 7.30pm and 9.30pm, he can pee as often as every half hour! I know there are key times when puppies are more likely to need to go, but I sometimes wonder if this is normal at his age. He has us up and down every evening taking him out to the garden and if we don't watch him, he'll stand there and pee on the rug! Your thoughts and personal experiences would be greatly appreciated.
