exercise exercise exercise.
When my dogs are getting tense and anxious and snippy with each other. I add more walks. The more they exercise the more relaxed and tired and less focused on each other they are.
My dogs have a huge fenced yard, but they need more stimulation that the same old yard every single day.
A walk a day on a different path or trail or road keeps them happy. And like i said sleepy dogs get along much better.
I also give them bones(something to chew) or a kong stuffed with a frozen treat in seperated areas of the house to keep them occupied
