I woke up at 4:30 this morning to Buddy vomiting in his crate. Not to be TMI, but it was very mucousy and not much food in it. I took him out, cleaned it up, walked him and put in back in (since it wasn't even 5 am yet!)
About 30 mins later, he did it again. This time no food in it at all. So, I cleaned up the crate but didn't put him back in. I gave him some water (big mistake) and he vomited again but it was all water.
What could be wrong? He's been very active and healthy . . . almost 9 months old and not a single problem!
