Is it true that a dog will know where did the other dog goes by just sniffing their backside (rear)? Whenever I bring my Spitz out for a walk and back, my other dog always sniff her backside. And same too when I brought the other dog out and leave the spitz in the house.

I think they do that to know exactly the odour of each other to don't get confused.This way they 'll know which territory is tehirs and which not.

I have heard that a dog does this to figure out whether or not it likes the other dog. kind of gross, but what ever. LOL! I guess they have to decide whether or not they need to be defending their territory or not. I could be totally wrong, lord knows i've been wrong before, but that is just how i see it. thanks for posting and God bless
