The most common diseases that pets suffer.

1. Conjunctivitis 

Both cats and dogs have a predisposition to eye diseases. Certain breeds are particularly susceptible to conjunctivitis, for example, a Persian cat and a French bulldog, as well as kittens and puppies. Colds, allergies, bacteria, injuries, a foreign body, dust or sand in the eyes, and poor hygiene can provoke the disease.

Symptoms : lacrimation, purulent crusts on the eyes, redness of the mucous membranes of the eyes, itching, swollen eyelids.

Help : eyes must be cleaned of pus, remove crusts and rinse, for example, with a decoction of chamomile. Under the eyelid of an animal, tetracycline eye ointment is laid. The doctor prescribes eye drops, with the advanced course of the disease – antibiotics.

Prevention:  monitor pet eye hygiene, flush eyes of kittens and puppies, take measures at the first symptoms of inflammation.

Symptoms : purulent discharge and smell from the ear, inflammation of the skin around, itching, pain. The dog shakes its head, tilting it towards the sick ear. Otitis is dangerous in that a perforated eardrum, inflammation of the membranes of the brain, which, in turn, can lead to the death of a dog, can occur in a neglected state.

Help: clean the sore ear with cotton swabs and apply an ointment containing zinc. The veterinarian can prescribe antibiotics to the sick pet, cleaning the sick ears with saline and special drops.

The disease is transmitted from animal to animal through saliva and blood. The incubation period can last from several weeks to several months.

Symptoms: violent form of rabies is accompanied by lethargy of the pet, shyness, later – anxiety and aggression towards people. The animal refuses food and water, which is one of the characteristic signs of rabies – a throat muscle spasm occurs in an infected pet.

Later, the animal develops salivation, paralysis of the muscles and vital systems of the body, which leads to death.

During a mild (paralytic) form of rabies, animals become affectionate and try to be near the owner. Their lower jaw hangs, saliva begins to liberate profusely, it becomes difficult for animals to swallow food.
