It's so hard

Sounds to me like his collar is embedded into his neck...

No, not at all. It was just rubbing against his neck. It happened to Alaska too.

What kind of collar is it? A rolled nylon collar? She should try a flat collar. Sores on his feet could be from not being used to walking outside or from scratching at the door, a wire kennel, or anything else.

It's a nylon. What is a flat collar? Thanks for the help

Leather works for dogs that can't wear nylon for that reason. Not sure what the sores on the feet could be caused from, but maybe from running on hard floors too much.
