For 3 years a ran a dog kennel with my (now)ex-fiancee, she was a groomer and would give every dog a bath and haircut before sending them home, meanwhile I took care of feeding, cleaning kennels, playing with the dogs, we had a few regular clients who's dogs had medication that they didn't like taking. With a little bit of patients and work, I was able to get the dogs to take their medication without issue, even making it easier for the owners to give the dogs their meds when they were home. I love dogs of all sizes and breeds, "dominant breeds" don't scare me. I have found that dogs that are aggressive to humans were raised that way, breed has nothing to do with it.
