i have used matetel on my last 2 matings, first time last year, took her when the ferning was strong, result was 12 puppies my biggest litter, just had a new bundle arrive, good litter of 9 so i think it is great, you can also use it again 21 days after matings and if you get ferning again it is a good indication she is pregnant, i did this both times too and it was right about that too. i recommend the matetel :)
