my yorkie is aggressive. I have had her 2 months, she is 5 years old. I have an eskie and
[COLOR=green !important][COLOR=green !important]sheltie[/COLOR][/COLOR] also. She is aggressive with the sheltie, when we play with the sheltie or show the sheltie attention. This has been hard on everyone. CC (yorkie) came from a home where she was aggressive with the other female yorkie they had, but we hoped she was aggressive because the other was also a yorkie and female. Both of mine are males. All are fixed. She is not aggressive all the time, just maybe once every week or two, but has escalated from snapping to actually sinking her teeth in, and now the sheltie, who is very shy and timid, is fighting back. Am I fighting a losing battle
