Ok. I need some ideas. I just added a new puppy to the family a week ago. She is 8 wks old and her and my 3 1/2 yr old boxer play together they even sleep together, but when it comes feeding time he gets really aggressive toward her. I have been feeding them seperate and feeding her in her crate, he was fine this way at first but now when i get the dog food bag out he automatically gets agressive toward her. Do ya'll have any suggestions i do try and correct him but doesnt seem to matter. Everything else is fine she can play with his toys jump all over him but food or treats is a no go. Also i can tell he gets depressed some when im holding or playing with he has been my only baby for 4 years and i dont like to see him hurt. Was wondering if this will pass. Any suggestions will be appreciated.
