Why does my dog go crazy after i bathe him

because he hates water and hates getting wet.

Dogs in the wild don't worry about bathing the way humans do. It's almost against their nature to bathe, so your dog goes a little nuts afterwards because he's uncomfortable and likely cold and trying to dry himself off.

I beleave it's because he is scared & wants his freedom

The sensation of lathering and bathing your dog ruffles his fur and makes him itchy. This is why they run arounf rolling on the ground or carpet after you bathe them. Think of all that fur your ruffled up, they just need to roll and wiggle around.

Because they feel good there body is relaxed like ours gets and they want to dry their faces on anything they can find. Clean and cooled off.

Because you washed his scent off him. They run around rubbing all over stuff trying to get their scent back.
