My two dogs are very possessive and I'd like to get them to share both with me and each other. One is a 2 year Cavalier mix that I've had for 6 months and the other is a 7 1/2 yr old JRT that I've had for only 9 days. Both are female. Now that I've removed all toys and bones from the floor, they're finally getting along peacefully and occasionally even playing with each other. However, when I do let them each play with a toy, I have to monitor the situation very closely. If one of them has a toy that the other one wants, a fight is inevitable. Neither one wants to give their toys to me either. They will retrieve the object to play fetch and come back to me but won't give the object up. They growl if I try to take the toy. Also, I think they have not yet sorted out which is the dominant one, although it's hard to tell. They both walk through doors simultaneously and both cover each other's pee. I'd like to get it to a point where they're happy to share with me and each other. Any advice would be great. Thank you.
