Do you have Nutrical?? i'd be giving him some of that for sure. you can try anything really... see if he will eat something soft like yogurt or cottage cheese... no chewing involved... apple sauce... peanut butter.... will he eat his treats?? (That's how i know JUST how sick Layla is
) and i'd say if you can't get him to eat anything by tomorrow just call the vet and see if this is a side effect of the K or else it is just he is feeling crummy because he is teething (they are like babies like that) Layla for the most part was ok when she was teething but she had days when she slept the whole day and woudln't eat. Can you give him a wet wash cloth that has been in the freezer for a bit?? that should feel nice on his gums... you might also want to try baby food... try the veggies. they have less stuff in them to keep them fresh... dont' go overboard on ANY of these things because they might upset his tummy . let me know if any of the food works!
