As soon as he came home, we ended up running him back in to the ER as he started to physically blow up again (he was extremely bloated and not moving anything through his digestive system and thus, filling up with gas). They sent him home with some motility drugs in him and told us to give him some Gas X. He slowly recovered, enjoying an extended stay in the house and things appeared to be back to normal. However, just under a month later, we noticed that he didn't have much of an appetite and was getting lethargic. David took him back to the ER and they concluded that he must have an internal bleed somewhere and that there wasn't much they could do (they could have done transfusions for a few days and then try to open him back up to find the bleed, but it didn't sound like a good option). I ended up leaving work to meet him at the ER where we got to say good bye to our buddy of 8 and a half years.
The kids took it pretty hard (and we did, too - more so than we would have imagined!). Mia didn't sleep well for a week or so and Fynn still doesn't completely understand where Jonas went. We made a pet gravestone for him, which I think the kids enjoyed doing with me, and we have it back in the wooded area of our yard so we can 'visit' him.
It's still hard to believe that he's not hanging out in the backyard or isn't going to be there to greet me when I pull into the garage every night. He's not there to bark at the random people that walk by the house or howl at the train or emergency vehicles that go by. Or, you know, his random adventures in which he would get lost at the farm and disappear for days (weeks) at a time. He is greatly missed. Bye buddy.
