I have two dogs, and one is a full male kelpie. He is a bit of a dummy, and lately he has been going a bit feral at the other dog, and even at me. He is at least four years old (I suspect he could be six or seven).

At the moment he is one kennel, barking, heckel up, lips curled, at the other dog who is minding her own business. I say he is a bit of a dummy, because the other dog, if she decided to go him, he'd be dead.

A favoured 'trick' of late, he sits or lays at the edge of one of the squares of grass, and will not let the other dog near. Barks and carries on like a real feral, even if she is just looking his way from the other end of the yard. It's like he's not wanting her to get to that piece of grass or something in it (but there is nothing there).

I don't want them to get into any more fights (they are fighting more and more over food bowls, even though I feed them away from eachother), and if he is like this with the other dog and me, then I am sure he will go the kids too. He snapped at Steph a bit before Ryan was born I think, and then he went me as I scolded him. But, having said that, last week, Steph was in the dog yard with me, and the Kelpie rolled over for her as she rubbed his belly.

I have had a few interruptions trying to type this, and he has been barking the whole time. He never used to bark unless there was something around, now he's becoming a bit of a pest with all his barking.

Does anyone have any ideas, aside from finding him a new home? And does anyone think I should just get him a new home? Because, unfortunately, I don't trust him at all.
