I have a Basset Hound Mix that is 6 months old. I also have a Maltipoo who is 14 human years old. The two do not get along. My 5 pound Maltipoo, Brooke, keeps trying to get control over my 6 month, 45 pound, Marley. Marley keeps on trying to sit on or lay on Brooke. I have tried numerous things but nothing has worked. Now, Marley has chosen to eat Brooke's poop not her own mind you....just Brooke's poop. I have tried meat tenderizer, pumpkin and now something called Forbid which the vet gave me. Nothing is working. I am thinking it is more like a dominance type thing???? Any thoughts?
