I have a beagle and a shepherd mix. They get along great and are always playing or relaxing together. What I notice sometimes is when they are playing sometimes one or the other one will have the hair on the back of their necks go up. Is this a bad thing or is this part of playing. I appreciate any help from people with multi dog families.
When they do this they are not violent just playing as usuall
