Hey guys,
I am new here and I am glad that I found this site, it has a ton of information! I live in north Carolina and I am owned by 3 yorkies. Hugo 9, Chloe 5, and Harley (my recent addition 17 weeks).
When we got our newest pup Harley at 9 weeks, he had a small open font, which has completely closed.

He had terrible separation anxiety, which I know was probably from him being parted too early from his mother ( will never get a pup younger than 12 weeks old again). The separation anxiety has gotton better except at night. We had been letting him sleep in his crate in our bedroom to stop the crying and that has worked, but after we take him out early in the AM he doesnt want to go back to sleep. Hes a whinner!! Our other 2 dogs sleep in a large pen together in our living room, but Harley wants no part of that. I have tried to gradually move him out our room as I would like for him to sleep with the others, but he cries for hours and we give in.

ANy advice???
Another problem I have noticed with him, is I think he may have some sort of psycological issues. Example, when I am prepping their food or when I take him out of his crate, he runs around and around in circles. He does it at other times also. He will not stop running around in circles until you stop him. I am thinking of mentioning this to my vet because I have never seen a dog act like this before
He is proving to be the most difficult puppy that I have had yet.
Thanks for any advice!
