thanks for the replies...
dog is kennelled and the tail was bleeding nearly every day. He's 2 1/2 and funnily never did it in his previous kennel. He's tried bandages but it was to no avail.

The tail was docked 2 weeks ago and he trialled yesterday and although he went back about 3 lengths he had done nothing for two weeks so it wasn't a surprise.

I'll keep u all posted! thanks again
