Yes, there are some disadvantages to wearing dog life jackets. Here are some of them.
The life jackets are to be worn over the whole body of the dog. They might be problematic for him during the hot summer season because they cannot let the body breathe on its own.
Moreover, they also keep his body in a certain position that helps him to swim with all four legs in use. So, the dog might not get tired earlier, but e might definitely get frustrated.
He might try to get out of it as dogs are not aware of clothing manners. This can get him in difficulty or emergency situation.
They can cause some sweating meanwhile the dog is in the water.
So, they can be pretty warm and untrained, or pet dogs might not like it.
Another problem associated with dog life jackets is that they have some extra bulk and padding material because they are used to keep the dog floating over the surface.
Dogs might not like this because, being animals, they are used to live freely in their body. They already have protective mechanisms in their body, so making them wear an extra thick piece of cloth can get them in a problem.
Dog life jackets must be kept as hygienic as possible because a dirty life jacket might also cause irritation.
If they are worn on the body all day long, they will eventually not let the skin breathe, and hence it might get rashes or marks on the dog’s body.
This can also make your dog irritated and frustrated. Make sure that they are trained to use it.
