Needs to go out every 2 hrs. But is fine all night. Likes people and is curious about what is going on. Is fine with other dogs or cats. Doesn't really play with toys, likes to be left alone, food and treat driven, and likes walks. Takes his 1/2 tablet in his food for a slight heart murmur. Quiet dog..
