Fiancee and her sister work for the same company, both have training scheduled last week (fiancee Sunday-Wednesday in Florida, her sister Sunday-Friday in NY).
I had agreed to watch soon to be sister in law's dog (he usually stayed with us most weekends, as his brother is our dog). She brings him over on Sunday, and he wasn't looking good at all. Very sluggish, moving slow, etc. She says he was just at the vet, got a shot, and should be better after the fact. Sleeps the rest of the night.
Monday I go to work, he hasn't eaten since the day before. I get home, he poo/pee on the floor since he can't hold it anymore. Still doesn't eat. I speak to SIL, she gets a vet appointment scheduled for him next day at 6PM. Sleep downstairs and constantly monitor him, getting about 2 hours of sleep.
Tuesday isn't looking any better. Still hasn't eaten, now can barely walk due to no food. SIL calls vet, moves appointment to 8AM. Bring dog in, they take a look, and transport him to the Vet ER. Proceed to ball my eyes out in the car.
Turn out he's got pneumonia, cost of care will be somewhere between $1500-$3000. SIL wants to try treatment, but they discover a severe bacterial infection, and can't guarantee that he'll recover. I get a call at 930PM from SIL saying she's going to put him down, and wants me to be there for him. Proceed to see him off to a better place, and then cry myself to sleep.
Wifey supposed to return Wednesday around 7. Flight gets delayed. Then she misses her next flight because they never announced it. Eventually gets home on Thursday around noon.
To say that was the toughest week I've had to endure is an understatement. I've got an enormous soft spot for animals, and to see the little guy suffering like, AND to have to be the one to be there for him on his last journey, that was absolutely crushing.
Sorry for feels, but I needed to get this off my chest.

Rest in Peace, Baxter.
