Sam seems to be on the mend so all is not lost. He is still not 100% but he seems pretty good.
French Heartworm may be the culprit. It is not the same heartworm that is found on the continental US but something unique to Europe and maritime Canada.
Fingers crossed here.
I hope to be grouse hunting Christmas week and a cousin asked me to guide him moose hunting. He hasn't been big game hunting before so needs a hand. Looking forward to Christmas week.
