I have had some sort of animal in my house since I can remember from dogs to cats to little critters! For my older, bigger, hyper pup we had a professional trainer train us on how to keep him under control, works wonders!! I am completely comfortable with all types of dogs from Chihuahua’s to Pits. The type of dog you own is my last concern, the safety of your pup is my first! My current pup is Biggie, just a big ole cuddle bug who has anxiety at times. Ive been working with him and he has gotten significantly better, that being said i now also have experience with hesitant dogs who need a little more time to adapt!
