when someone who KNOWS bloodlines finally decides to comment there is nothing negative to say about the dog and his lines.
Of course, there is nothing wrong with the DOG.
I get him, bring him home... He's great! Listens.. .Is good with my son.. and with my other dog. But wait? Still not good enough? How dare I take a picture of the new dog with our dog or our child. God forbid we like the dog enough to take a picture... he might rip one of our faces off... You're kidding right? Get real.
You might take your own advice to "get real"... right now, you are imagining a fantasy world where the new dog is and will always be Lassie. Yes, the dog listens well, reacts appropriately to your son and your other dogs, etc. There's nothing wrong with the DOG, he sounds like a solid boy with a stable temperament. It's just that you're setting him up for failure the way you just threw him into the household and allowed your Chihuahua to attack him, then expected him to gently but firmly "correct" the offending critter. Thankfully he did not. The new dog is on his best behavior right now, so you're not apt to see his whole personality come out for a few weeks. He may become less tolerant of the yapping attacks of the Chihuahua, reach his limit, and one good bite and shake and it's all over. We are trying to help you prevent that from happening!
I try and take advice from some of you but there is a point to where it just gets ridiculous and no matter what I say there is someone who want's to dissect it.
Since it is Thanksgiving, you could be thankful for the time that people have spent "dissecting" things out of concern for you, your family, and your new dog. If you don't want advice, why are you asking?
Read again about the "two week shutdown", and why it is important. We're trying to help you successfully integrate your new member of the family. Remember, a number of us have seen things happen before, or even experienced them ourselves... this aint our first rodeo. You can poo-pooh our advice if you like, and maybe you'll get lucky, but what we're saying is that you can make things a lot safer, smoother, and easier if you want to.
He sounds like a great dog, please do him justice.
