I've always taken my puppies to the vet for vaccinations and wormings but with my next litter I'd like to do them myself. I've been looking up as much info as possible, but I'm having trouble finding a wormer for puppies under 5lbs. I'd like to know what product you recommend for vaccinations & worming and what worming dose you use? As well as where you purchase it from. Thanks so much for any advice
