Over the last 30 + years I have kept and work all sorts of dogs. German Shepherds, labs, border collie, spaniels and a BMH. I presently have 3 springers (7, 9 and 12 years old, 2 still working and one retired) and the BMH.
Had the four dogs out for a short bit of exercise this morning, nothing much as it was getting warm. Dogs had a short run about and then a splash in the burn. Put the dogs back in their kennels. The two younger spaniels share. Although these two dogs usually get along they can have a bit of "debate" now and again but nothing serious.
Shortly after being put into their kennels I heard a bit of growling going on and shouted my usual "enough" which normally puts a stop to any further nonsense. A while later I went into their kennel to replace the cow matting that I had power washed earlier. As I went into the run both dogs ran into the sleeping compartment. On leaning over the compartment to close the top the older dog suddenly turned and sunk his teeth into my elbow and held. I could see the look on the dogs face "oh sh!t what have I done" and he let go but bottom line is that I now have a painful and punctured elbow and the big question of why and what am I going to do about it. In 30 + years of dogs I can honestly say that this is the first I have been bitten by my own dog.
Anybody else and I would be saying "one way walk" but although this dog can be aggressive toward other male dogs he is a very responsive, loyal dog and has never shown any aggression towards me or anybody else. Don't think it is heat related as he was not hot after being out and their kennels are in shade, could possibly be that he was in a wary/alert disposition after the growling session but whether to give him the benefit of the doubt????
