Sheltie Aggressive at Times
(Ft. Lauderdale, FL)
My sheltie likes to chase the birds in my backyard when we let her out of the house. She does it very aggressively and once they are gone she bites our plants in half or tears them out of the ground! We've tried holding her back so she will relax first before we let her chase the birds, but nothing seems to help. She exhibits the same behavior in the house if she sees someone outside. She goes crazy and tears up anything near. She is six and we adopted her about 6 months ago. At all other times she is the perfect lady.
