When we purchased Jack, we should have known something was up! He cried ALL the way home, he was scared of all the dogs at the dog park, and screamed if they came in 10 feet of him, he always acted as if we were gonna beat him at all times, he took FOEVER to housebreak, but he is great now, he acts aggressive to people and dgos he does not know, even though he has been in Petsmart's training classes and graduated. He acts like they are killing him when they cut his nails, they always say..." do you touch his paws?" and we massage his paws all the time. we are so embarrassed. we feel horrible for him too, but we are at our wits end as it were. It is putting a huge strain on our marriage as well, WHAT CAN WE DO??? we were told not all dogs like people and other dogs, but this is crazy! HELP!!!!
