In our experience, dogs are generally more willing to take oral medication than thier feline counterparts. Usually, a special treat that can easily conceal a pill or tablet will be readily eaten. Some suggestions for this are: canned dog food, peanut butter & a bit of bread, soft plain white bread, hotdog, or Greenies Pill Pockets ®/MD.
We recommend hand feeding these pill/treat morsels to be sure that the medication is actually ingested. If you find that your dog is searching out the medication in these treats, try setting up a quick series of treats. Give a few tid-bits without the medication before and after the pill/treat combination.
