Harvey thats quite normal for two dogs who live together to do that if they can't get to the other dog, if anyone is stupid (and a lot are) to let their dog run up to my gate in the back, then you can guarantee there'll be a fracas between two of them.
Casey was diffusing the situation by doing nothing, did he yawn as well. I usually find leaving them to get on with it, as long as there is no bloodshed, works. Lots of noise and spit, sounds like a murder, but nothing to worry about.
Just done some ironing, thank goodness, it was on my mind, and I kept putting it off because my backs been sore.
Eileen, you must be worn out, no wonder you're heading off for a weekend, you need a month I expect
