Poor dog. That looks like bite marks to me. If the guy
from animal control chose not to deal with it, I'd call them
again & talk to someone else. Most AC depts. let individual
officers make their own judgement calls most of the time.
It's possible he's afraid of the dog or the owner himself. I'd
call again & try to be there to talk to them when they come
out. Maybe they'll send another officer this time. What a shame.
I am glad you got Tasha out of there.
