Please Help Holmes Recover

Carl and I rescued Holmes one month ago, and we immediately feel in love with him. He is an affectionate, awesome dude who is a great big brother to our husky and cat. He had a major seizure today out of the blue, and we are trying to save him. The vets think he'll recover, but the first 24 hours of care is estimated at almost $2000, and the next 3 days of hospitalization could run $7000. We don't want to give up on him because of the money. Anything helps and is greatly appreciated. Thanks for reading about Holmes.
