Behavior Issue With Male Rescue Australian Shepherd
We have a male rescue Australian Shepherd who has behavior traits that we are concerned about. He lives primarily outside with a dog door to the utility room where he eats and sleeps, rests, etc. We have a large fenced front and backyard for him to run.
The problem is he is good with my husband and others inside the house but when he is outside he will not let my husband or others pet him. He comes close but not actual petting.
He also has bitten my husband multiple times when he is in his shop or working in the yard. He does not like power tools or mowers and weed eaters, now even if my husband rolls the car jack around in the shop he bites him. Last bite was on the knee and it is badly bruised.
We have had him for a year and a half now so my husband has tolerated well but we have to stop this behavior. All suggestions are appreciated.
