I'm sure Phantom will be fine. Ozzy was done a week ago. He was very groggy and quiet when I brought him home. It was upsetting to see him like that but once I gave him a little water with honey he perked up. My vet sent me home with some liquid painkillers and I gave him a dose about 2 hours after I brought him home. He had started whimpering a bit. But by 7pm he was eating a few kibble, still a little wobbly but much more himself. By the next day..BAM!!! back to his crazy self
