Can you tell me what you use, which is best and what they are actually necessary for? I have many a time clicked a dog's link from show results which then takes me to INFOdog. I then need to sign up for an account to view anything at a certain amount per month depending on the type. May I ask which type to choose, for what reasons do I use that type and if there is a way of viewing INFOdog data without paying a monthly fee? TIA.
