First of all, I am so happy that your babies are OK...I have heard to many horror stories with dogs hurt due to them wearing collars in the house...the last one happend to a German Shepherd puppy...his collar got caught on the plastic thingy at the end of the verical blinds, you know the cheap ones at Walmart....well the puppy ended up strangling himself as he made it worse trying to get out, now this dog was create trained...the owners where in the next room and did not hear a thing...they where and still are devestated by this.....please beware !!!
Laurie.
