Quote from page 2 of the letter:

"...Regarding the reduction of population of stray animals, the National Veterinary Office supports the proposed in the document strategies and measures.

The opinion of the experts is that the major elements for controlling the population of stray dogs is permanent identification of pets, upkeep of national register, promoting neutering by introducing a tax for non-neutered animals and controlling the population of strays by neutering and their release back to the site of capture until their steady reduction and consequent gradual collection of the dogs in shelters."
