I've always been around animals and love all types. I have many years of experience and have trained my own dogs. I know doggy CPR and basic healthcare. I don't have a fenced in back yard but I do have a wireless electric dog fence that I use for my 11 pound dog but can be used on dogs up to 100lbs. I also have a kennel in the back yard with a dog house for shelter. I have tons of experience with all breeds as I also use to volunteer at the local animal shelter and I've owned 4 rescue dogs. And I've doggy sat for my friend who has a pitbull mastiff and a Shiba inu. Large dogs do not scare me i just ask that they be friendly and house trained
