I have bred Airedales and Miniature Schnauzers. I no longer breed but remember I had a couple of girls who were genuine Alphas. They even didn't squat to pee but half crouched and lifted their leg to mark their territory. I think it is just an Alpha and personality thing. Humping is pretty normal. Males do it and I had a schnauzer male who had been neutered as a pup and still humped everything. He even humped my airedale girls on the shoulder. They tolerated it for the most part. Pretty funny.

I consider myself somewhat of a Terrier Expert. I have owned trained and bred Min. Schnauzers and Airedales. I grew up with Airedales and Welsh and Irish Terriers. Rat Terriers are in alot of those breeds. I love their energy and they are very vocal. I think the Trick with all Terriers is to train them to want to do what you want them to do. Clicker firm voices yelling etc. never works. I even had someone using a pinch collar on an Airedale. Never works. My experience also includes feisty jack Russels One who was deaf and learned sign language. She was almost put to sleep at the shelter because of her barking. Terriers are not known for shedding. but can use brushing, I also use a detangler spray and gentle wire brush for their hair.

I had min. schnauzer who was a nipper on ankles when anyone tried to leave. He was a sneaky biter and definitely an alpha. He never broke anyones skin. What I did is train him to sit stay whenever anyone got up to leave. After I released him he would tear toward the door and bark.

Chicken and Rice is fine, but a hassle to cook with. I also try mixing Canned Pumpkin plain no seasoning. Mixed with Kibble. Ratio for kibble two to one. I also use Organic chicken broth. It helps to get the vet to check out your pets digestive system.
