Do you sign up for free samples for your pets?

I don't normally sign up for free samples for my pets. We have 4, 2 dogs and 2 cats and their kind of picky when it comes to their food. They like to stick to the same brand and flavor and have a really hard time switching. It has taken about a year but we finally have them all set with their food. It agrees with them and we aren't seeing any issues with any of them. We do have a dog that has allergies, so we have to give him a food that has no grain in it at all. Poor little guy. He enjoys the food we have him on now though.

I'm not one to keep switching my pets food because I worry about stomach upset and things like that. I do sign up on the websites of the food we do purchase to keep up to date and receive coupons when they are offered.

Hope this helps,
Danyel
