just wanted to know which revolution to get? we're getting a mini dashound, he's 8 weeks old, so do i get the one for puppies and kittens which is puppies and kittens up to 2.5kg or the one for dogs 2.6kg to 5kg? can we wait to take him to the vet til the new year? or does he need to see a vet as soon as possible? only cuz a lot of days over the xmas they're only open for emergency things. Also, at what age do we need to desex him? man, i've never had a puppy before lol, i dont know what to do, its almost like having a baby!!
