Here are some of the possible reasons:
1. Her anal glands are swollen and causing her discomfort. To remedy this the best thing is to take her to vet.
2. She could have foxtails or something rather that is poking her in the butt, causing her to scratch. To remedy this check for anything unusual around where she is scratching and remove it if you can do so without hurting her.
3. I've heard that parasitical worms can cause such symptoms. If she is also rubbing her butt on the carpet, it's a pretty good sign. To remedy this you can try to diagnose the type of worm she has (as they have their own signs) and give her some wormer. Or you can take her to the vet and they may be able to diagnose the problem.
Your dog could have worms, get a de-wormer from your vet.
because it wants to.
Answer 2:
Typically, a dog chews their butt because they are itchy. So, I would check for fleas.
there is a special spray so the dog will stop chewing anything you spray the spray on..........you can get the spray at petsmart
cut them off.
Give him enough food ofcorse
You could be extreme and muzzle the dog in the car. Another option is to buy a truck:)
Get rid of the fleas. Flea allergies are the number one reason for visits to the vet!
well if its a baby you have to train it if you don't it probable wont stop
Get one of those lampshade things
Try getting a "simple solutions" puppy pad holder, more toys to entertain your dog, or crate training.
Your dog may be chewing on the stairs because he is teething. If your dog is a puppy this is a likely cause. When you see the dog doing this, say no and give the dog something safe to chew on. Your dog may also be chewing on the stairs because he is bored. Try playing with the dog, and giving him interesting toys to play with.
Could be that the dog has OCD, in which case, keep her from chewing on it even if it means physically restraining her head with a head cone. Could be that the nipple was already causing her discomfort and she started chewing on it to alleviate that discomfort. Take her to a vet.
It's dog's butt.
What you need to do is get an empty spray bottle and fill it with water.When the puppy or dog bites you, you spray it. it should stop bitting you.Whenever the dog bites you spray it as said
