The fact that there are dogs that are always hungry can be linked to the breed or its crosses. However, it is also related to certain diseases such as obesity or hypothyroidism. This is due to the fact that the desire to eat is regulated, among others, by a hormone called leptin. Do you know what is the best large breed puppy food?
Leptin is secreted by adipocytes, fat cells that are made up of 95% of fat. This hormone acts several hours after the dog has eaten and indicates that the dog has already eaten enough food.
We could think that those dogs with obesity and more volume of adipocytes would produce more leptin and, therefore, would eat less. Nevertheless, when so much amount of leptin exists in serum, resistance is produced and the body stops responding before this hormone, reason why the animal always is hungry.
4 breeds of dogs that are always hungry
The breeds of dogs that are always hungry are those that, due to genetics, usually have a higher amount of fat or a certain tendency to get fat. It is very important to control the amount of food that these dogs consume and, in addition, that they carry out sufficient physical exercise daily. Next, we offer you some examples of these breeds:
The Labrador Retriever -in the image that heads this article- is, besides one of the noblest dogs as a domestic animal, one of the breeds of dogs that are always hungry.
This type of dog is originally from Great Britain and its use is mainly as a hunting retriever. It is not a very old breed, and it is approximately originated at the beginning of the 20th century. It could have been used by local fishermen to bring in fish, as they are great swimmers.
Their skin and coat are rich in fat which isolates them perfectly from humidity and cold. A low physical activity and an excess of food causes this type of dog to fatten quickly and to produce a resistance to leptin that makes these dogs always hungry.
The golden retriever breed has a similar origin to the labrador retriever, but this breed is also used for hunting with firearms. With a larger bearing than the Labrador and not so much tendency for fattening, the golden is one of the dogs that are always hungry.
They are dogs with a high level of activity, very intelligent and that, quickly, get bored if they do not have the sufficient training of smell. If they are not properly entertained, they can direct their deficiencies towards food.
The pug is a breed that originated in China, but developed in Great Britain, where it arrived during the 16th century. These dogs are characterized by their compact, well-developed body, but always with some fat that should not be confused with obesity.
The also known as pug seems to be always hungry; moreover, one should be careful because they can ingest non-food objects. Among other things, this occurs because of resistance to leptin.
The ancestor of the bulldog was known as bandog, a dog used for fighting with bulls. This information dates back to the mid-17th century. Later, during the 19th century, a version more similar to the bulldog we know today appeared. It was at that time when it began to be used as a show dog and, thus, it became very affectionate and friendly.
Since that time, the bulldog has become stubbier, due to the fact that it accumulates more adipose tissue under the skin, which presents many folds. This characteristic makes it a breed very prone to suffer from skin problems.
