I suspect so too on the poison. Bear is home today. He made a rapid recovery and now shows no symptoms what so ever. It is as if he was never sick to begin with. The vets ran all sorts of toxicologies and tests and still can not figure out what happen. On his discharge papers they wrote suspected ingestion of medication or toxin. They told me to scour the house to make sure there is nothing he could get into.
He isn't the type of dog to just randomly eat anything on the floor. He is pretty picky, but it does not mean it is not impossible that he licked up a dropped pill.
The dead owl had me confused as well. It was laying on the ground, in perfect shape, no injuries. it looks like it just fell off a branch or something. I do not use poisons for pest control but I do not know about my neighbors. Still I am a good distance from the nearest neighbor. There is a pond near by but he never goes to it. He isn't allowed out of my sight and the only time he is out of the yard is when he's in the pasture with me. It doe snot mean he hasn't wandered out of view a time or two, but I doubt he's gone to the pond.
It is truely a mystery. They had multiple vets look at him and his records at the animal hospital and none could come up with any concrete conclusion. I trust this animal hospital. They have treated many of my animals in emergencies and have always given them the best care possible.
I knew he was feeling better because as we walked out to the car, he had the nurses laughing because he did this prancing hop thing he does when he's happy, all the way to my car. When we got home the first thing he did was race over to the chicken coop then to the pasture to check on HIS flock.
I'm just glad to have him home. Thank you so much for the suggestions and support. I fwd all the info to the vet while he was in the animal hospital and they looked into everything suggested.
