My Samoyed used to love to eat apples when we would visit the orchards and get cider in Vermont. At $2.29 a pound here, I rarely buy them for myself and the one time I offered them to Rocky, he had no interest.
I did read an article recently that said that an apple was one of the worst fruits you can buy in the grocery store now because of the pesticide build up in the skin. It was really an informative article and recommended that if you had to buy apples, then you always peel the skin off. Mostly it said to stick to fruits that had tough outer skins like bananas and pineapples....etc. I'll try and find the article again and post it.
