Most pure breed Pugs that you see will have twisted tails. This adorable twist is a result of a hundred years of selective breeding. However, some Pugs do have a loose tail. There are a few reasons behind that:
The puppy might not be feeling well. He/she may be experiencing some health issues.
The Pug tail curls usually begin to vanish at old age. Their muscles may start to weaken, or arthritis sets in. Both of these things can cause a Pug’s tail to go straight.
Younger puppies uncurl their tail a lot. But there is no need to worry about it. As they grow, the Pug tail tightens up. It will stay twisted more often.
An injury to the tail can also result in a straight tail. This is why it’s so important to watch children around Pugs. That little curly Pug tail may be too tempting not to pull.
Inflammation can also result in a straight Pug tail. If a dog has inflammation in its rectum area, he may hold his tail low. There are other signs that their straight tail is due to inflammation. If your Pug has a straight tail, it’s useful to check for these other symptoms to rule out inflammation.
Some dogs suffer from Limber tail. Generally, these dogs are working dogs, which are Pugs are not! It’s worth noting, however, as a Pug could be affected by this.
This is caused by strain or overworking the tail due to swimming, excessive exercise, or exposure to cold weather. Any breed can become inflicted with Limber tail.
It is worth noting if your Pug has been swimming or in the cold.
Poor breeding practices also lead to straight tails. Some breeders try aggressive methods to achieve a double curl. Not all these methods are successful.
The cross between two loose tail Pugs also produces puppies that have little curling.
