Seresto collar for small dogs

Small dogs rarely live in the yard. Usually, owners prefer to keep miniature pets in the house, carefully look after them during walks and often think that their pets are reliably protected from blood-sucking insects, and if any especially lucky flea gets to the dog, a monthly treatment with a special shampoo or spray will be enough, to get rid of it.

Alas, it is not so! Fleas are extremely tenacious of live creatures. These are real travellers who move on stray and domestic dogs and cats, on clothes and shoes, penetrating even into city apartments. Their eggs can lie in the grass of a backyard or park for a long time, waiting for your pet to walk on them, and ticks can move on animals and birds. It is impossible to guarantee that a small dog will not encounter parasites!

But the Seresto flea & tick collar for small dogs can provide you with this protection. Easy, high quality, safe. Literally one movement – and fleas no longer threaten your family pet!

How safe is Seresto collar for puppies?

The active substances that make up the collar and are designed to kill fleas are selected so carefully and sealed in a plastic base so cleverly that they practically eliminate the risk to the life and health of small dogs even weighing up to 8 kg and puppies over at age from 7 weeks old.

Ingredients poisoning parasites are released in microscopic doses, spreading through the hair, but do not harm the dog. Moreover, you can continue to play with the animal, and if you allow your pet to sleep in the same bed with you, there is no reason to give up this habit – a flea collar will not add to your health problems.

The owner will have to remember only two things:

  • Remember to check from time to time whether the plastic strip is loose enough. Puppies grow quickly, and after a couple of weeks, an accessory that used to fit may be too tight.
  • Don’t let your dog chew on the flea collar. This is unlikely to have irreparable consequences, but indigestion and symptoms of poisoning – salivation, vomiting and heavy breathing – are quite possible.
