Maggie (Deaf) (Female) (Spayed at 6mo) is a 13 yr old 11 pound chihauhau mix and has lost her hearing. Riley (blind)(male) (neutuered only 4 mo ago) is a 7 yr old, 15 lb Jack Russell and has been blind from cataracts since he was about 2. These 2 dogs have lived together and shared everything (toys, food, people..etc) since Riley (blind) was a puppy. Riley (blind) has been getting very aggressive towards Maggie (Deaf) lately. Whenever Maggie (Deaf) approaches his space, he can't see who/what she is since he's blind so he sounds off a little warning growl. Maggie (Deaf) doesn't hear it and keeps coming. I think Riley (blind) interprets this as Maggie (Deaf) challenging him. It seems to be getting worse and I have to jump in and yell and pick little Maggie (Deaf) up and when I do he's then jumping and biting at her. I finally had Riley (blind) neutuered several months ago and he seems even more aggressive now! What can I do? They have always stayed home together while I work but now I'm afraid after all these years Riley (blind) is going to hurt Maggie (Deaf) all because she doesn't hear him. Does anyone have any training tips on how to handle this? Riley (blind) is very smart and trainable. Maggie (deaf) is hard to work with since she can't hear me.
