I'm kind of like your wife....afraid of big dogs, particularly German shepherds. Though I really really like Labs and Great Danes.
I've had 4 Westies though, and would have another in a heartbeat, but other half thinks dogs only belong outside, and I think they belong inside. It's been an ongoing battle for years and until he realizes that dogs in his prior "lifetime" weren't properly trained, there won't be any more dogs here.
We do have 3 cats, and he suggested the other day we go to the shelter and get another one. This from the man, who 19 years ago when we started dating, detested cats!
Most dogs belong inside with their pack of people. Some breeds do need to be outside, but most are miserable being apart from their loved ones, US.
Southern idea, dogs in the barn, people in the house did not indear me to my ex MIL that put my taco dog outside and the poor thing got a rip snorting skin problem from the grass and bugs. Hell of a mess for the poor thing, back was close to open soures when we got home after only one day away. One does not tie out a dog the size of a small cat in the country, darn a big bird could have eaten him all up.
I have have had BIG dogs, Rotties, a St. Bernard and a Shepard with enough land for them to run about. after they bounced about and did what ever they needed to do, they were in 30 minutes or less back at the door wanting to come in and check us all out, keep an eye on us. This is their job, to watch over us, they cannot do that chained up to a dog house in the back yard.
My new hubby raised in tenements in the city never had a dog and when we met he was not a dog lover. Behind his back I got another Taco dog, weighed about a pound and Hubby was aghast until the little fella climbed into his shirt and went to sleep on his chest. Next thing I knew Hubby had the dog in his pocket or his lap, dog slept over his pillow and -----I no longer had a dog, HE did.
Just as one trains children, husbands and dogs is much alike. A well trained dog is a Joy, a well trained child is a Joy, a well mannered husband is precious.
