I have two cattle dog mixes - one is mostly Catahoula; the other we think is mostly Australian Cattle Dog. Both are pretty alpha. The Catahoula is an almost 14 year old female; the ACD is a male, about 6. Both adopted from rescue groups, but 12 years apart (we've had the Catahoula the longest). They are both quirky and I am partly assuming this is because they are pretty smart and don't live on ranches, so although we are fairly religious about getting them exercise it probably still isn't enough. The funniest thing we've noticed is that the younger dog, the Australian Cattle dog mix, likes to walk back and forth behind our floor length curtains - very slowly, making sure that they graze his back and his head. Any ideas WHY he does this? He is a fairly high anxiety dog but we give him a pretty significant amount of petting and attention. The only thing I've come up with is that he is trying to sooth himself. The old Catahoula has always done things like stand between me and the counter when I'm cooking, or tap the back of my knees when she wants something. I have been told this is a herding thing. Is the "curtain walk" also a herding thing?
