Tail-Chasing
When puppies chase their tails, it's like babies grabbing their toes. It's a way to explore their bodies. It's not usually a problem unless dogs do it all the time. See if you can distract your pup. If he would rather chase his tail than eat or go for a walk, it's a problem. You may need to talk to your vet about training or medication.
Crotch-Sniffing
Dogs like to sniff each other’s bottoms, but it's different when they nose up to someone's crotch! It's not bad manners, according to your dog. Dogs can get a lot of information about other dogs by sniffing around down there. They probably get the same info by sniffing people, too. If your dog’s nosiness bothers you -- or the people they sniff! -- obedience training may help.
Scooting
It’s common for dogs to scoot or drag their bottoms across the ground after doing their business -- especially if their stool is loose. But if a dog scoots a lot all day, see your vet. Scooting can mean impacted anal glands, which you should get your vet to treat. It could also come from having a tapeworm.
Humping
Watching your dog get personal with the new sofa may make you cringe, but it’s normal. For many dogs, humping feels good or relieves stress. It's more commonly done by male dogs, but females do it too, sometimes. It's OK to look the other way in most cases. But if they're humping people, they may be trying to show dominance. Call them off so they don't bother anyone, and talk to a trainer or vet for behavior tips.
