Means of protecting dogs from ticks - advises a dog veterinarian
Tick Remedies for Dogscan be divided into two groups:
repellents that have a repelling effect
insectoacaricides that cause the death of parasites.
Types: tablets, drops at the withers, collars, as well as sprays and ampoules with essential oils, biomagnetic cards and ultrasonic key rings.
All protective equipment, except tablets, are not absorbed into the blood.
There are vaccines for pyroplasmosis, but their main task is not to prevent the disease, but to reduce the number of deaths. Vaccination does not replace dog treatment with protective equipment.
Drops at the withers
After application, the active substance is distributed throughout the subcutaneous fat, accumulates in the hair follicles and sebaceous glands of dogs and is gradually released, scaring away or destroying fleas and ticks. You need to buy droppers with drops strictly according to the weight of the dog, apply directly to the skin and do not bathe the dog 3 days before and within 3 days after treatment. The onset of action is 3 to 5 days after application.
Carefully read the instructions: what weight the pipette is designed for, how long the protection is guaranteed, from what age the dog can be used, is it suitable for pregnant and lactating bitches.
The advantage of collars is that they last 5-7 months, but they must be worn without taking off. The main disadvantage is that the active substance is released from the collar, and it is difficult to ensure constant monitoring of the presence of collar contact with hair and skin in dogs. The beginning of the collar action is 2 to 3 days after the start of use.
The meaning of the use of sprays in their repellent (scaring) action. Spray the whole dog, not forgetting about the ears, face and stomach. Sprays begin to act immediately after application.
Until the coat has completely dried, the animals must not be allowed to lick the preparation.
There are tablets based on fluralaner and on the basis of afoxolaner. The duration of action of drugs based on fluralaner is 12 weeks, based on afoxolaner - 4 weeks, the tablets cause the death of parasites. Drugs are not given to puppies under the age of 8 weeks and weighing less than 2 kg. In the period of lactation and lactation, preparations based on fluralaner are allowed to be used, drugs based on afoxolaner are recommended to be used under the supervision of a veterinarian.
The main plus of the tablets is that the drug is only in the circulatory system and does not stand out on the skin. Therefore, tablets do not lose effectiveness in sun exposure or frequent water procedures. But they do not scare away ticks, but kill them only after the parasite bites the dog.
Biological preparations based on vegetable oils
The pluses include the lack of addiction to them in insects and the danger to human and animal health. These funds are usually approved for use by pregnant, lactating, sick and weakened animals, puppies, as they do not contain toxic substances. Their only effect is in the additional repellent protection of the dog before each going out (but not instead of fixed assets!) Do not forget that the effect of sprays decreases in the sun after bathing!
Other means of protecting dogs from ticks
In extreme cases, preventive injections. Their validity period is from 2 weeks to 1 month. Such protection has 2 significant disadvantages: firstly, the reaction to the drug is individual and it is rather difficult to determine the dosage and the duration of the drug. Secondly, this drug is toxic to the liver.
Magnetic cards and ultrasonic charms
They are safe for animals and humans. Do not have a toxic effect. Approved for use in nursing, pregnant and weakened dogs. They can be used as additional protective equipment.
The active substances of dog protection products against ticks
Most effective consider pyrethroids of the 2nd generation: permethrin, deltamethrin, cifenotrin, flumetrin, fipronil, pyriprol. The safest for humans and dogs are permethrin with fipronil.
Pyrethroids - These are environmentally friendly substances that do not migrate in soil and water, do not kill earthworms. At the same time, synthetic pyrethroids are toxic to parasites.
Permethrin It is recommended not only for use in veterinary medicine, but also in medicine (WHO recommendation), and in everyday life.
Permethrin quickly acts on ticks, and at the same time repels and destroys them. True, there is a drawback - in the world the active substance breaks up.
Note! Permethrin is dangerous for cats: they can be poisoned. If both a dog and a cat live in your home, it is necessary to use carefully protective equipment containing permethrin. If this is a drop, do not allow the cat to contact the dog immediately after treatment! Permethrin collars are best avoided.
Organophosphorus compounds (tetrachlorvinphos, karbofos, methyl mercaptophos, dichlorvos, diazinon, chlorpyrifos, etc.)also taken as part of anti-tick preparations. But they have very high toxicity (I-II hazard class for humans), are easily absorbed through the mucous membranes, damaged and undamaged skin, and irritate the skin. Because of this, and also because of the low reliability of the dosage at the moment, European countries and the United States refuse FOS, replacing them with safer means.
Carbamates (proposkukr).They are less toxic than FOS (II-III hazard class for humans). Although carbamates have the same mechanism of action as FOS, they are eliminated from the body, and the risk of poisoning is lower. In addition, they are quite safe in terms of carcinogenicity.
Amidines: amitraz. These substances, like carbamates, have a contact neurotoxic effect, but mites do not develop resistance to them. They can not be used for young dogs and small animals. When using substances of this type, the likelihood of allergic reactions is high. Toxicity is lower than that of FOS and carbamates. Amitraz is not considered a human carcinogen.
