Nurti-cal and Sammi go hand and hand...She wakes up in the morning and she knows she is getting her "VITES" (that is what she knows them by) She will sit in the kitchen by the cabinet and look up until someone satisfies her nutri-cal craving

We used to get them at our vet but they charged more there...
Walmart sells it also

This is the cheapest I have found it...So since there are 3 dogs in the house who use it we usually get about 6-8 tubes at a time
