What is cushing in dogs? The advice and information platform for all horse and dog enthusiasts.

English Translation:

Cortisol is a corticosteroid, a hormone produced by the adrenal glands from cholesterol. Cortisol plays a crucial role in metabolism and the processing of proteins, carbohydrates, and lipids. It is a stress hormone, just like adrenaline. Cortisol prepares the body for a fight-or-flight response. However, a (prolonged) excess of cortisol is harmful to health and disrupts various bodily processes. Cushing's disease can occur in all dog breeds but appears to be more common in Dachshunds and Toy Poodles than in other breeds.

Symptoms of Cushing's in Dogs

Symptoms of Cushing's range from common to less frequent:

excessive drinking and urination
a pot-bellied appearance
thin coat, hair loss, bald patches
panting
muscle weakness, lethargy
diabetes
urinary tract infections
pigmentation spots

Causes and Treatment of Cushing's

Cushing's disease is most often caused by a benign tumor in the pituitary gland, a small hormone-producing organ in the brain. The adrenal glands work closely with the pituitary gland to regulate cortisol production. The pituitary gland produces the hormone ACTH, which stimulates the adrenal glands. When the pituitary gland malfunctions, the adrenal glands may produce too much cortisol. In most cases, this is the cause of Cushing's disease. However, in about 15% of cases, a malignant tumor in the adrenal glands causes Cushing's. It is essential to determine the underlying cause! If your dog shows symptoms of Cushing's, always consult your veterinarian. Often, your dog will receive medication to manage the disease, but in the case of a malignant adrenal tumor, surgery is necessary. Most dogs respond well to treatment.

Supporting a Dog with Cushing's

Proper nutrition and supplements can help support the health of a dog with Cushing's. Supplementing with Omega-3 fatty acids may help lower cortisol levels and has a positive effect on coat and skin health. Your dog's gut health is also important, and probiotics can play a role in this. In some cases, dog food formulated for diabetic dogs may be appropriate. If your veterinarian finds that your dog has high blood fat levels due to Cushing's (a possible side effect of the disease), a low-fat diet is recommended.

Humans and mammals have a system of tiny transmitters and receivers in their bodies, which ensures that signals from cells go to the brain and vice versa. This way, the brain knows if something is wrong somewhere and can send helper substances or other cells to the right location to address a disturbance, intruder, or problem. This system is called, with a difficult word, the 'endocannabinoid system'. And no, this is not science fiction!

Cannabi-whats? This unknown system keeps your dog healthy!

Humans and mammals have a system of tiny transmitters and receivers in their bodies, which ensures that signals from cells go to the brain and vice versa.

This system is called, with a difficult word, the 'endocannabinoid system'. And no, this is not science fiction!. If you've never heard of the endocannabinoid system, that's not too strange. Scientists only discovered in the early 1990s that humans and mammals have an endocannabinoid system at all. This system restores balance in cells in cases of pain, inflammation, and disruptions to the immune system. Your dog also has an endocannabinoid system. It is important for many bodily processes. For example, in oxygen transport, the proper functioning of the nervous system, bone formation, the gastrointestinal s...

Clove for dogs, what does that do?

Giving cloves to your dog might sound a bit strange. But it's actually quite logical. The clove plant produces strong cannabinoids. These substances help to keep your dog healthy, for example in case of joint problems. Cloves are therefore a good choice instead of CBD oil from cannabis.. Every mammal has an endocannabinoid system (ECS). The ECS was discovered about thirty years ago and consists of a system of receptors that exchange signal substances. This way, signals about the health and balance of the body are delivered to the right places. In short, the ECS monitors the physical and mental balance of an animal (or human) and ensures a good resistance to illness and external influences. A very important system, therefore, that influences a wide range of physical and mental co...

What does the mineral silicon do for dogs?

Silicon is an important mineral for all mammals. But not everyone has heard of silicon. Silicon is essential for the formation of bones, muscles, tendons, ligaments, and cartilage. Silicon is also an important mineral for dogs that should be included in their diet. What is silicon and what exactly does it do?. Silicon ensures that the body itself produces the necessary building blocks for hair, nails, tendons, ligaments, and joints. Silicon is also good for bone formation. Various studies have shown that this mineral stimulates the production of collagen and joint fluid. Silicon is particularly important for young dogs in growth, for dogs with early joint problems, and for dogs that are very active. For dogs of breeds that regularly suffer from joint problems, it may be wise to give silicon preventive...
