Rescued Dachshund with Aggression Issues
Hi, we recently adopted a 6yr old male Dachshund who was rescued from a puppy mill, very sweet and loving little guy. We currently have an 8yr old female Great Dane and a 3yr old male Dachshund in our home, both sweet dogs. They have been getting along fairly well but within the past week, the new doxie has shown some signs of aggression towards the Dane, nothing triggering such as food or a toy, but it starts with a growl and then he charges at her. Luckily we've been able to stop him before any damage could be done. Can you explain why this might be happening and what we can do to help all pups get along happily?
