I don't OWN a pittie, but I do sit for many of them. Since we board multiple dogs a time, it's always possible that a client's dog may interact with a bully breed. In fact, my profile says "bully breed friendly" in all caps.
Before the meet and greet I always say, "Since we do board multiple guests, are there breeds that Fido does not get along with or that you prefer him not be around?". This lets me know if they are anti-"certain breed" before I even meet them in person.
Keep in mind, most anti-bully dogs are not interested in being educated otherwise. They have firm beliefs about certain dogs and they are not going to be easily swayed. If you encounter someone being nasty about your pup, I would let them know that while you respect their opinion, your dog is a well-behaved and well socialized pup. Then, let them know its not a good fit. You don't need that negativity, and Nash doesn't need it either.
I am not a Pitbull owner myself, BUT I do have a number of friends that have some wonderful Pitbull family members. My best answer is to tell them that "a good dog is a good dog." A dog is also so much a product of their environment...and I'm sure they have a loving and nurturing home with you! :)
If a pit bull brings on negative, then don't tell. I will never work (training) with pits again. Very unpredictable dogs. Cannot trust them. & I suppose this is the exact thing you don't want to hear. Won't ever own another pit again.
yu can trust them,but its the fact they cant trust humans!
I would acknowledge the clients concerns, and request an opportunity for them to meet you and your pitbull so they can see how your dog behaves. I hosted a pitbull that I was told was a "bulldog mix" before the meet & greet. The dog was obviously a pitbull mix. ALWAYS MEET & GREET BEFORE HOSTING!
