hey guys at the shelter i work at theres like 3 large male dogs that really dont get along. Before a few weeks at the yard they would growl at eachother and fight everyday so always keep them separated now, but im not sure so healthy. Every time when i bring them out to the yards or back inside and one passes a kennel with his enemy inside they both go crazy... Whenever they are on their own they are pretty well behaved and respectful dogs, its just when they run into eachother all havoc breaks loose, and if they actually meet it is a guaranteed fight. It ruins what could be a much more peaceful shelter...Is their a way to train them to accept eachother or is continued isolation the best option?
