Drastic Behavior Change in 6 Year Old Yorkie 4 years ago my 2 year old Yorkie Pluto had a FCE. He has been doing great since other than a bladder stone surgery. He has always been the sweetest dog ever no aggression, no barking, well trained good behavior. He got a little sister Sophie 2 years ago (long hair Chihuahua) they have been thick as thieves since the day she came home. About two months ago at bedtime Pluto attacked her as if she had hurt him in some way but she was nowhere near him. I separated them and checked both out everyone was fine tried to go to bed again and same thing happened. Needless to say since then they do not sleep together. Now he is doing other strange things not laying in the same places, acting differently, he will wake up with a start and seek her out and act aggressively towards her she will immediately roll onto her back and become submissive and they might play for a little while or he might chase her around kind of barking at her and sort of bullying her then at other times he wants nothing to do with her. He also seems agitated a lot of the time. I have had him at all three vets and they have no answers whatsoever it is almost like they dismiss him. One of them even said he has just been through so much already I just dont know what else to do for him. He seems to have good days and bad days with whatever this is the good days he is almost his old self. The bad days like today he seems miserable not so much like he is in pain or anything just like he cannot get easy as if he is just so angry about something like when you cant get something bad off of your mind. His aggression is solely directed at Sophie no humans or even other animals. On the good days they still cuddle together and play with their toys together and he seems to love her more than anything. The vets have checked him out and his blood, stool, teeth, everything and say everything is normal. I tried a low dose seditive one of them suggested and it actually seemed to make him worse.....Any advice or suggestions would be greatly appreciated. |
