How often do your dogs have their teeth cleaned at the vets?

[caseysmom]

We usually pick up a pack of uncooked "soup bones" when we go to the grocery store, which contain some marrow and they're relatively cheap, around $1.50 a pack for two larger to four smaller bones. What are your bones "labeled" as because I have the hardest time finding UNCOOKED bones in my area...

My dad always asked the butcher for bones for the dogs, they were usually free. I haven't done this since my dogs don't go outside I wonder where they will eat the bloody bones,,,,on the sofa
