Dental disease is one of the most common reasons for visits to the vet for both rabbits and guinea pigs. Since their teeth grow throughout their lives but are not sufficiently worn down in their current living conditions, pathological changes to the teeth often occur.
Approximately one third of all dental diseases are caused by hereditary malocclusion of the jaw and molars. In particular, the breeding of short-headed breeds has led to the opposing molars no longer wearing down sufficiently during the grinding motion of eating and consequently growing excessively. This can result in sharp points on the teeth, which can cause painful injuries to the mucous membrane of the mouth and tongue. The molars can grow together over the tongue, significantly impairing the normal chewing process.
However, the majority (70%) of all dental problems are acquired and caused by an incorrect diet. To ensure normal tooth wear, rabbits must spend an appropriate amount of time chewing their food. Nutrient-poor, fiber-rich roughage such as hay or fresh grass, but also vegetables, are ideal for this purpose. If the food is too rich in nutrients, such as grain pellets or sweet fruit, which the animal only needs to eat a little of to feel full, the chewing process is too short to wear down the teeth sufficiently. The teeth grow beyond their normal length and sharp edges and points form, which can injure the gums and tongue and make chewing even more difficult.
Malocclusion can also lead to excessive strain on individual teeth. The excessive pressure causes the teeth to grow into the jaw instead of out. This can result in abscesses and injuries to the nasal cavities or eyes. The gastrointestinal tract of animals is also not designed for easily digestible and nutrient-rich feed and can react accordingly with flatulence and diarrhea.
Dental disease in rabbits and guinea pigs can manifest itself in various symptoms. Not all signs are immediately apparent to the owner, as the disease usually develops gradually. Both species are prey animals and are accustomed to hiding illness for as long as possible, which is why dental problems are often discovered at a very late stage.
The following symptoms may indicate an existing dental disease:
If your pet shows one or more of the above signs, take them to a veterinarian as soon as possible so that any potential dental disease can be diagnosed and treated at an early stage.
First, the veterinarian will ask you about the symptoms and when they started, and will make an initial assessment based on their examination. Changes to the incisors can already be detected and identified during a general veterinary examination. However, in order to diagnose molar problems or diseases, the treating veterinarian will need to examine the animal's mouth more closely. In most cases, a thorough examination is only possible under short anesthesia. X-rays of the head are often taken to identify misaligned teeth, any bone changes in the jaw, or hidden abscesses.
Depending on the type and extent of the changes, the teeth can be ground down and shortened by a veterinarian under anesthesia using special equipment. In the case of acquired dental diseases, however, the animal's care and diet must be adjusted in the long term to prevent the problems from recurring or worsening.
In the case of inflammatory changes or abscesses in the oral cavity, antibiotics and anti-inflammatory drugs are used to prevent the spread of inflammation and potential blood poisoning. Abscesses often need to be removed surgically. Similarly, severely altered or inflamed teeth must be removed completely.
IMPORTANT: Overlong incisors must never be shortened with pliers, clippers, or other unsuitable tools. The pressure of the pliers can cause the tooth to split lengthwise, and this split can continue under the gum, which can then become inflamed. The tooth may splinter, resulting in painful jaw abscesses or pulp inflammation.
Dental diseases in rabbits and guinea pigs generally have a favorable prognosis. Early intervention and species-appropriate feeding are crucial for successful treatment. In cases of hereditary malocclusion and secondary diseases, recurring problems are to be expected, although the intervals between episodes can be significantly extended with an appropriate diet.
In the case of hereditary tooth misalignment, dental problems cannot be completely prevented. However, acquired dental diseases can often be prevented very effectively with certain preventive measures. First and foremost, it is important to ensure that your pet has a species-appropriate diet with sufficient fiber-rich food so that their teeth are worn down naturally. Regular check-ups at the veterinarian are also very important in order to detect and treat any changes at an early stage.
This disease is a mostly congenital vascular malformation of the liver that was first described in 1949. The "shunt" is a connecting vessel that directs blood from the body's circulation past the liver directly into the main vein and thus unfiltered to the heart. The liver's inability to detoxify the blood leads to gradual internal poisoning of the animal.
Pulmonary stenosis, also known as pulmonary artery stenosis, is one of the most common congenital heart diseases in dogs and describes the narrowing of the pulmonary artery, which originates in the right ventricle. This heart disease is extremely rare in cats.
A withers fistula refers to any disease of the horse's withers that is accompanied by inflammation and fistula formation.
Many people find birds fascinating. And some feathered friends can not only live with "their" human for a very long time, but also form a close bond with them. But what do you actually need to ensure that everything is perfectly prepared when your feathered roommates move in?
One topic that many horse owners don't like to think about is that horses need to be transported from time to time. It is important to be prepared for this and to actually practice loading and transporting your horse in advance. Because when it suddenly comes to "putting the horse in the horse trailer," some animals can be more stubborn than expected. Loading and transporting horses causes a certain amount of stress for them. Even the most experienced horses, who travel to competitions every weekend, will show some signs of tension. But transport is a matter of practice; the more we make it a routine, the easier it becomes for the horse. To get a horse from A to B, it goes without saying that the towing vehicle and horse trailer must be compatible and that the technical requirements must be met. It is also very important to carry the horse's equine passport with you.
Birds such as budgies, beos, and parrots can not only learn to talk, they are also capable of performing small tasks. With enough patience and a few training tricks, humans and birds can have a lot of fun together. And the results are often impressive!
Syncope refers to fainting or circulatory collapse that occurs suddenly without warning and leads to a temporary loss of consciousness in animals. The dog collapses suddenly and shows no signs of life. After a short time, it regains consciousness and behaves as it did before the syncope.
Ectropion is a malposition of the eyelid that mainly affects the lower eyelid. The outer edge of the eyelid is turned outward and hangs down, which is why it is also referred to as a "drooping eyelid." This malposition prevents the eyelid from closing normally, leaving the eye permanently slightly open.
Tracheal collapse is a condition in dogs that causes the windpipe (trachea) to collapse. It mainly affects small breeds such as Yorkshire terriers, miniature Spitz, poodles, and Pekingese. The condition often manifests itself in the first few months of life, sometimes with severe breathing problems.
The tendons are part of the musculoskeletal system and act as the connecting links between the muscles and the skeleton. They consist of strong, flexible tissue, transfer energy from the muscles to the bones, and thus enable targeted movement. Their special structure, consisting of parallel connective tissue fibers grouped together in bundles, gives them enormous tensile strength and elasticity. The flexor tendons of the front legs are particularly exposed to extreme stress in horses, as more than half of the body weight has to be carried by the forehand. Tendon damage is one of the most common causes of lameness, especially in sport horses. In most cases, the structures affected on the front leg are the superficial flexor tendon, the deep flexor tendon, the suspensory ligament, and the fetlock joint (see diagram). As there are very few nerves and blood vessels in the tendon tissue, healing is very slow.
Myiasis is the medical term for fly maggot infestation in rabbits, which occurs primarily in the warm summer months and in injured or weakened animals. The disease is often underestimated, but can be life-threatening for rabbits.
This muscle disease, which was only discovered in recent years, occurs primarily in Quarter Horses and cold-blooded animals and is characterized by the storage of excessive amounts of glycogen (animal starch stored in cells) in the horse's muscles. It is known as polysaccharide storage myopathy (PSSM).
