Why do dog dogs bite their tails?

When you first see your dog biting his tail, it may seem like crazy dog behavior and that there are no specific reasons why he does it. On the contrary, this behavior in dogs indicates that something is bothering your dog, and he will need your assistance. There are a few possible reasons why dogs bite their tails, and they include:

  • Parasites – internal and external
  • Impacted anal glands
  • Bad hygiene
  • Allergy
  • Tail injury
  • Behavior problems

No matter the main cause, your dog will need your help to stop this behavior. For some of the reasons mentioned above, you will have to take your dog to the vet for examination. So, let's take a closer look at mentioned reasons.

1. Parasites

There are two main types of parasites – internal and external. Both can be a reason why your dog bites his tail. External parasites are more common, including fleas, ticks, and mites. All of them can cause discomfort for the dog.

Internal parasites include tapeworms and roundworms. While tapeworms will be transmitted over flea bites, roundworms will be transmitted over contaminated stools of different dogs. Either way, your dog will need proper care and therapy to eliminate parasites from its system completely. Your vet will prescribe you the best treatment for your dog's needs.

2. Impacted anal glands

All dogs have anal glands, and they are placed on your dog's anus. This anal gland will produce fluid when the dog defecates. This fluid serves for territorial marking. If this fluid is not expressed, the anal gland could get clogged and cause a lot of pain and discomfort for your dog.

To ease discomfort, the dog will start to chew and bite that area, including his tail. Also, your dog could begin dragging his butt on the floor. You must take your dog to the vet, or you can express anal glands yourself. We recommend that you seek vet help.

If your dog doesn't receive proper grooming and other basic care, he could start having problems with bad hygiene. His response could be tail biting if his anus area gets itchy. Also, bad hygiene could cause skin irritations and infections, and your dog will bite infected areas.

4. Allergy

If you catch your dog biting his tail, allergies could be a reason. Different allergies can cause discomfort for your dog, and he will respond with biting to remove his discomfort. Allergies can be caused by fleas, dermatitis, inflammation of the skin, etc. Talk to your vet about your next steps to remove allergies from your dog's life.
