Always go to the vet & be sure if its nothing medical 1st. If he gets a clean bill of health then its time to stop allowing him to run your household. This means no sleeping on the bed, not up on furniture, make him SIT for EVERYTHING (petting, food bowl, playtime etc anything that he considers valuable) If you need to find a trainer in your area go to APDT.com then click on trainer search & enter your zip code. Good luck!!
