If your usually energetic pup seems unusually tired and lacks interest in playtime, it could be due to the drain that parasites can cause on their energy levels. Coughing or breathing difficulties can also arise due to certain parasites affecting your dog’s respiratory system.

A perianal fistula is a type of tunnel that develops in the skin around a dog’s anus, creating what looks like a hole in the skin. This condition can be uncomfortable and problematic for dogs. Recognizing signs of a perianal fistula can help in identifying this issue.

Firstly, if you notice your dog experiencing pain or straining while trying to go to the bathroom, it could be indicative of a perianal fistula. Additionally, they might face difficulties with their bathroom habits, showing signs of constipation or diarrhea. Keep an eye on their stool as well.

The presence of mucus or blood can be a signal of this condition. Dogs with perianal fistulas often resort to chewing or itching their backside, indicating their discomfort. Another sign is if your dog avoids sitting down or seems hesitant to do so. This reluctance could be due to the discomfort caused by the fistula.

Moreover, watch out for sensitivity around their tails and rear end. Dogs with perianal fistulas might react aggressively if someone tries to touch these areas. Behavioral changes such as depression, aggression, or restlessness could also be linked to this condition.

Although German shepherds are thought to be more susceptible due to their tail position, any breed can be affected. If you notice these signs in your dog, seeking prompt veterinary attention is crucial.

A veterinarian can provide a more accurate diagnosis. They will recommend appropriate treatment to alleviate your dog’s discomfort and improve their well-being. (Dog Biting Base of Tail But No Fleas)


6. Foreign object

If your dog has something trapped in or near their rear end, like dirt, feces, grass, or even something it ate accidentally, it might scratch or itch the area in an attempt to get rid of it. If you notice something stuck on your dog’s backside, you can gently remove it if it’s on the outside and visible.

However, it’s important to avoid trying to pull out anything from your dog’s backside. This could lead to harming their intestines. Instead, it’s a good idea to let the veterinarian take care of removing anything from that area. It’s quite common for dogs to get something stuck around there, especially if they’ve been exploring outdoors.

Visiting the vet is the best approach if you suspect something might be causing your dog discomfort or itching. The vet can safely remove anything causing trouble. They will also ensure your furry friend stays happy and healthy.


7. Anxiety

 If your dog can’t stop scratching back there and there’s no obvious health problem, it could be because of something called a “compulsive disorder.” This happens when your dog feels stressed or worried, repeatedly making them do the same thing. When your dog is experiencing anxiety, there are several steps you can take to help them feel better. Firstly, consider using calming products to soothe your dog, such as calming sprays or diffusers.

These products can create a more relaxing environment for your furry friend. Secondly, ensure your dog gets enough physical activity. Regular exercise through playtime and walks can significantly reduce their anxiety levels. And it’ll promote their overall well-being.
