My dog Bentley was very social with bigger dogs. That was until I took him to a Petsmart puppy training class. The trainer and handlers were not paying enough attention to their dogs and a couple of the large dogs had trampled my Bentley and it scared him to death. And the trainer had the nerve to yell at MY dog for barking during class. Now Bentley just barks at bigger dogs and won't go near them, unless they are very calm. I now have him enrolled in a beginner obedience class at a REAL training facility and I feel he is at no risk of getting hurt (But he still barks at the bigger dogs in our class).
Just remember training is always a good idea. Just do your research and find a reputable trainer.
Good Luck! |
