Why does my dog sniff other dogs’ butts like it’s a hobby

Butt-sniffing is basically your dog’s version of Facebook stalking. Dogs have an amazing sense of smell, and the glands around another dog’s tail carry all kinds of info—like their age, gender, diet, mood, and even health. It’s a socially acceptable way for dogs to introduce themselves, say, “Hey, who are you?” and learn all the juicy details. Think of it as their version of reading a detailed bio. So, while it might look weird to us, to dogs, it’s perfectly normal. Just make sure the sniffing party is consensual—nobody likes an overzealous sniffer!
