oh boy.. lol..l dont' think we have facedthat many but we have had our challenges! Layla used to have HUGE separation anxiety and now that is gone THANK GOD. She still has issues when she is around too many other dogs that she doens't know, she gets protective and snaps at them. Currently we are having problems when i pick her up at the babysitters she comes between my legs and growls and snaps at the other dogs as if to say, this is MY mom, stay away... it is frusterating because i want to pick her up when i see her but i dont' want to reward this behaviour... i think there will always be issues to overcome
