I have young male 11 months with very high energy drive. he is back to spending his days at work with me which gives him plenty stimulus and exercise. I am seeing a problem starting to develop when we get home. I have a female pit/mix 5yrs 30#that stays home. The young male has always showed great interest in her and she will have little interest in him and on occasion be playful but mostly tolerate his rough play. On our entry both dogs energy level goes up and i can calm the dobe but he is so focused on her and only wants to interact with the female. We are not having fights but he is so rough it really has to be checked. This is not a entry issue only, he does shadow her and can get pawsy. I am only making him stop and sit and getting him to focus on me. How do i get him to respect her space?
