Does a dog swim

Answer 1

A fish breathes by bringing water into its mouth and forcing it out through its gills. This causes the dissolved oxygen to reach the blood and enter the fish's cells.
There are many different types of animals that live in water. Some of them like dolphins, whales and frogs are not able to actually breathe under water. Fish and other aquatic animals however have gills that filter the oxygen out of the water.
Oxygen is dissolved in the water much the same way carbon dioxide is dissolved in your soda. Most sea creatures have gills that can extract that dissolved oxygen as the water passes over them.

Answer 2

Fish,whales dolphins etc. have gills.

The simple REAL answer to this is they have gill's and the only animals that live underwater are fishes,dolphins whales etc.

EDIT: This is simply false. Whales and Dolphins do nothave gills. They are mamals, with lungs, and must come to the surface and breathe air.

Answer 3

ya they invented the doggy paddle

Not all dogs can swim, the ratio of dogs being able to swim is about the same as the ratio of humans who can swim. Even if a dog can swim, like humans there are circumstances i.e. strong current, when dogs do drown.

Answer 4

Sharks can not hold their breath because they do not have lungs to store the air in. They rely on water passing over the gills to mantain oxygenated. Above water they can survive until their gills become dehydrated and the supply of oxygenated blood runs out.

Answer 5

Yes, many dogs are capable swimmers and can enjoy activities such as swimming in pools, lakes, or the ocean. However, not all dogs are natural swimmers, and it's important to introduce them to water safely and supervise them closely.

Answer 6

It depends on the dog. I do believe that dogs are able to hold their breath underwater, especially ones bred for search and rescue.
