I have 4 dogs all mixed breeds Daisy is dalmatian mix, Princess is rottweiler mix, Lucky chow/black lab mix and Copper who is corgi mix, Daisy's 10 Princess is 9 going on 10 I believe, Lucky is 6 Copper is 3 or 4
Anyway my problem is Princess she has always been a scared dog when I got her she was abused she would be afraid of everything even a garbage bag but for some reason now she's being aggressive towards the other dogs especially Daisy for some reason, she has attacked Daisy twice, even tho Daisy drew blood, Princess has attacked Copper also, but the aggression is toward Daisy the most, Princess will growls at lucky but hasn't attacked her yet I don't understand why she is doing this now. Princess been with Daisy since she was 6 months well I believe thats how old Princess was when I got her going on what the people told me.
Also I notice sometimes when I give them treats bonies Princess will wait until all the rest of the dogs eat theirs and then will sit with her's and wait for one to come next to her so she can go after them. Don't know what to do, I don't want her attacking the other dogs and I also don't want it to get bad where she will attack anyone. Also Princess has growled at me when she would never do before.
What do I do?
