The FREE dog is on antibiotics. Evidently she has some parasite or bacteria or some such thing caused by a deer tick.
We have long used the clever method of wrapping her pills in something tasty. I prefer cheese, but the Doxycycline she is on calls for no dairy. So we have been using soft cookies, bread or pasta. Every so often tho, the FREE dog will get a taste of the pill concealed inside and spit out the whole mouthful.
To keep this from happening I hold another treat in my hand, so she can clearly see it as she eats the first piece. This causes her to gulp it down quickly so that she is ready for more.
