I have had dogs growing up my whole life! Big and small. I wanted to be a vet but couldn't handle putting down an animal! I care for any dog like it's my own and maybe baby them a lot! I've trained my own dog and have been around dogs being trained. I just love dogs a bunch! People are scared of big dogs but I have no problems! As long the as the owners doing their job it shouldn't be a problem. All dogs have the ability to be nice and as I said I believe it's how they're raised! I live on a lake so if your dog likes to swim that is an option! No worries thought I will bathe them once they are all done!
