I have noticed that our 3 month old Shih Tzu gets a little crazy in the evenings. I believe he is just overtired and excited. He won't settle for an evening nap as he needs to follow me around. He then becomes super hyper and the moment i sit on the sofa. He will jumps and nip at my feet. He becomes a different puppy(aggressive puppy)
I am wondering if i should just put him in his crate for his evening naps. The majority of his naps are in is crate.
