well I do not understand that separation anxiety thing as my sister keeps telling me to quit giving Lucy so much attention that she will get that ,now you are saying it is from taking her from her mother to soon,I will have to read up on that,as I do not want to see Lucy go thru that . My niece adopted a border collie that had that but when my niece would leave in in the car for 5 minutes she tore the inside of the car up, in that short of a time she did huge amount of damage,while my niece was at work, she loves animals and was really trying to help this one, but she just couldn't keep her very sad, and she was a vet tech at the time
