i have 3 small Yorkies myself house-trained and well-mannered. I'm able to keep up the energy with hyper dogs as well as slow and gentle with older dogs. I have no problem with Large Dogs I've been bruised up by some big dogs I've got no problem with physical pets. I have had pets with me every year of my life ranging from puppies to elder dogs to strays and rescues and I've yet to find one that hasn't liked me; Every dog's individual personality is different and needs to be adjusted to. As well as I have befriended dogs and gotten them house-trained I unfortunately do not have intensive training or have the ability to teach tricks or discipline. But other than that I feel like I have all the necessities to treat your companions right and have a blast doing it!
