RE: Which breed is most loyal/easiest to train?
Well..... ahem.... just look at the picture.
Biased...yes I am... but for good reason.
I have seen Labs do some amazing things. However, Labs tend to pick ONE PERSON to be their master. Sometimes its you, sometimes is one of the kids.... but, for the most part, they are one person dogs. Sure, they will be friendly to anyone, and they will listen for the most part.... but you can surely tell who runs the show.
Now, my Golden is for the most part the same way. He'll follow me anywhere, and gets so excited when I come home I'm worried he'll bust. But he will listen just as good for anyone else as he will me, and is hyper and happy, but well behaved. Just need to have enough room for them.
