How Long Does Heartgard Last A Few Husky Questions?

A few husky questions? - how long does heartgard last

Well, I asked last night, but no luck. So let's try it again?

First, what food would be better? I want to take a prey model raw diet, but I keep reading about this and it's really hard to swallow and no local butchers and slaughterhouses, so that I can not find the courage. Our adult dogs (SIBE / GSD) from TOTW and in spite of his food at all stages of life, I'm thinking about it somehow. I've recently bought a puppy from a Chicken Soup for the Puppy Lovers Soul (not the big races, but they could not find), but I read many places that large breed puppies have different nutritional needs, but nobody says exactly what to buy. So, if the premium is not now in question, what are you going?

Secondly, what brand of heartworm prevention do you recommend? I've always without problems Heartgard, but the vet really pushes new Interceptor. I really have no idea what is better, or if there is still a big difference.

And finally, I wonder about the use of diatomaceous earthWe monitor the earth for fleas / ticks, instead of using a chemical such as Frontline. I know that the essence of how it works and I had saved my little dog Adoptable Dogs used their sled dogs, and no problems with fleas, so I think it a try. Thus, questions uhm. Work with ticks? How much should I feed and how often internal parasites (I read that for the pups, the 1 / 2-1 tsp.)? I live in a rural area and have a large garden, as I'm going to court using DE? Or was primarily on the closed side to concentrate? And finally, how many times I have been loyal to working with my dog?

What was so long and so many questions, -;
Well thank you ^ ^
