@Soulfox -- I won't argue with you, but I do think that another easy problem to deal with is diet. The article has it right -- if you don't feed your dog the right food, your pup can wind up with liver damage or something far worse.
The question, though, is which dog food should you buy? That is a question for your vet. There is some good commercial stuff out there that doesn't cost as much as the premium brands and will provide great nutrition. Which commercial brands are good, though? Your vet will have that answer and he or she might suggest you do go with a premium brand.
