DirtDawg - I hope he recovers quickly. He sounds like a real jewel of a dog.
Last Monday I took him to our vet and started a regimen of amoxicillin. Now after a full week and a day he is perfectly back to normal.
He has seemed fine all weekend, but now he is truly himself!
Barking at any squirrel noise or sighting, chasing the birds back to the trees, sniffing for those damn raccoons and shitting in their general direction, anxious to go for his walks, smiling constantly and stealing the cat's bowl, etc.
Not sure if he is an actual jewel, but he truly brings joy into this household.
