When I first got Sasha (4-5 years ago) she had so many problems the first time she showed aggression with food was when I try to take her bowl from her I got her out of it she was letting me take her food, she didn't care if my cat went near her while she was eating she was really good for about two years then she started growling at my cat and went to bite me a lot then she was good for another year then me and my partner moved into our house were in now and he has a Maltese at first they were fine then Missy (the Maltese) started trying to steal Sasha's food which started her aggression again then dozer came into the house and Sasha loves him they adore each other. They are all fed separately in the last 3 or 4 weeks Sasha hasn't let me take her food off her, if she has a dentastick she will growl and run away if we walk past her.
I'm not sure what's changed nothing is different but when she launched at dozer today it was like she was a completely different dog she's never done it before and when she walked away it was like she didn't know what was going on she was so scared I took her inside after (I had to fix her ears from fly bite) and she sat between my legs shaking
