The decision to neuter is difficult for many dog owners. On the one hand, you want to see a change in behavior, but on the other hand, you are concerned about irreversible consequences. With a Suprelorin implant, you can test how neutering affects your dog's behavior and health without taking the final step right away. The implant can also be used for ferrets.
The Suprelorin implant contains the active ingredient deslorelin. This binds to receptors in the hypothalamus (part of the diencephalon). It then releases hormones, which in turn stimulate the production of gonadotropins in the pituitary gland (hypophysis). These have an activating effect on the testicles, which then release more testosterone (male sex hormone).
This leads to increased hormone release in the first eight weeks after the initial implantation. During this period, the testicles are therefore stimulated more intensively. However, oversaturation with deslorelin then causes the receptors in the hypothalamus to be downregulated. This causes testosterone levels to drop dramatically. This inhibits libido and sperm production, resulting in temporary infertility in male dogs.
The Suprelorin implant is approved for temporary castration of male dogs and ferrets. It may only be used on healthy, uncastrated, sexually mature males.
In dogs, the implant releases the active ingredient over a period of six to twelve months, depending on the dosage and weight. This makes it possible to test the effects of castration on the dog's behavior and health. The implant can also help suppress hormone-related undesirable behaviors such as excessive aggression or pronounced sexual behavior.
The biggest advantage of the Suprelorin implant is that its effect is only temporary. Unlike surgical castration, your male dog will be able to reproduce again once the implant has worn off. The implant is also a solution for male dogs for which permanent castration is not an option due to behavioral or health concerns. Compared to surgical castration, chemical castration is simple and non-invasive.
The Suprelorin implant takes about eight weeks to become fully effective. During this time, temporary behavioral changes and increased sexual interest may occur due to a brief rise in testosterone levels. Once the implant has worn off, it may take some time for the testicles to return to normal function. This should be taken into account for breeding dogs that are to be used for breeding again in the short term. In rare cases, the implant may not dissolve completely. This can cause problems if the implant is used repeatedly. Small male dogs weighing less than five kilograms have a higher risk of permanent inhibition of testicular function.
As with any hormonal treatment, side effects may occur with the Suprelorin implant. These include:
First, your vet will check your male dog's health and give you individual advice on neutering. Your dog will be weighed, as this determines the duration of action and choice of implant. The Suprelorin implant is available in two dosages. The lower-dose implant lasts for about six months and is suitable for medium-sized dogs. The higher-dose implant lasts for about twelve months and is used for larger dogs.
The implant is inserted subcutaneously (under the skin) into the skin fold between the shoulder blades. No anesthesia or sedation is necessary. Your veterinarian will disinfect and possibly shave a small area around the implantation site. The implant is injected with a special, slightly larger needle. After the injection, the skin fold is pressed together for a short time to prevent the implant from slipping out immediately.
After implantation, make sure that your dog does not lick or scratch the area excessively. Observe your dog's behavior, especially in the early stages, with regard to dominance, sexual interest, aggression, activity level, and eating habits. Regular veterinary check-ups are recommended while the implant is effective. Your vet will check your dog's health and ensure that the implant is working as intended. At the end of the effective period, you and your vet will decide whether to insert a new implant, perform surgical castration, or allow natural hormone function to resume.
The higher-dose Suprelorin implant is also approved for male ferrets. It is used to control reproduction. Male ferrets that have not been neutered often behave very aggressively, mark their territory with urine, and have a strong, musky odor. The implant can help alleviate these behaviors.
The duration of action and onset of action vary from ferret to ferret. Infertility begins between five and 14 weeks after the initial treatment. The duration of action can last up to four years. Therefore, the decision on when the next implant is necessary is made on an individual basis. Your vet will assess the increase in testicle size, the return of sexual activity, and may measure testosterone levels.
The Suprelorin implant is administered to male ferrets under general anesthesia. Treatment should be carried out at the beginning of the reproductive period.
Heart disease is also relatively common in our four-legged friends, affecting almost one in ten dogs. Heart failure occurs when the heart can no longer pump enough blood into the circulatory system, meaning that the body is no longer supplied with sufficient oxygen.
Urolithiasis, colloquially referred to as urinary stone disease, refers to the formation and deposition of various concretions in the urinary tract of horses. Although this disease occurs sporadically in horses, it can lead to serious symptoms and significant impairments. The deposits can occur in the form of crystals, grit, sand, or stones and are most commonly found (approx. 60%) in the urinary bladder. Geldings are more severely affected than stallions or mares.
What do these five letters stand for? This abbreviation comes from English and literally means "feline lower urinary tract disease." It describes all diseases of the urinary tract in cats that cause difficulty and pain when urinating. As a rule, almost exclusively indoor cats are affected; outdoor cats almost never develop this condition. Male cats are also more susceptible than female cats.
Vaccinations for horses serve as preventive healthcare and protect against possible diseases and their spread. Depending on what you want to do with your horse, different vaccinations are recommended and even mandatory for competition horses. All vaccinations are correctly documented by your veterinarian in the equine passport.
As a general rule, every dog needs a certain amount of grooming, some more than others. For some dogs, it is even worth taking them to a professional groomer. As a dog owner, you can also do some grooming yourself at home.
Taking in a foal and choosing the long road to happiness on horseback is a real adventure! It is an opportunity to form a bond that can mature over many years and to watch a foal grow into a horse. But it also requires commitment on your part.
Winter affects humans and animals differently than summer. The body has to adjust to the cold, darker season. We can also help our dogs get through the winter very well.
Did you know that color rats have a pleasant calmness and can bring a lot of joy to those around them with their friendly nature?
Thanks to improved preventive care, senior dogs are no longer a rarity. Similar to humans, they suffer from classic age-related ailments such as osteoarthritis, cataracts, and dementia. Around 20% of nine-year-old dogs and almost 70% of 15-year-old dogs suffer from dementia, also known as canine cognitive dysfunction syndrome (CDS or "dog Alzheimer's").
Fancy a little fun and games with your rabbit? Rabbits are intelligent animals. With patience and the right steps, they can even perform a "high five" or "sit."
What is a fun night of dancing for many people is unfortunately a sensitive issue for a lot of dog owners: New Year's Eve fireworks frighten our noise-sensitive four-legged friends and can lead to major problems.
Uveitis is an inflammation of the uvea, the middle layer of the eye. It can be divided into anterior and posterior inflammation and manifests itself through a narrow pupil and reddened conjunctiva.
