My sweet Scouty (right) died a few days ago. He and Bitty were litter mates and had been side by side 15 years and 6months.   
I can’t stand the thought of leaving Bitty home alone. It doesn’t happen often, I’m retired and hubs is self employed But there are times it cannot be helped. He sticks by my side or in my lap always (they both did), and sleeps with us. I hand fed both of them (no teeth).   
My question is should I get another dog to be his companion? I don’t know what he thinks about Scouty being gone.  Sometimes I feel like he is looking for Scout but then think that’s just my imagination. When our other chihuahuas passed, none of the rest seemed to even notice (we we had momma, poppa and three pups). Bitty is the last of them.   
Bitty is tiny, <4lbs right now. We tried fostering a puppy about a year ago and she beat both boys up just trying to play. It didn’t work out.   
My hubs wants a chihuahua puppy. I feel like a puppy that small probably wouldn’t hurt Bitty but he would be annoyed by puppy antics. I don’t think he wants to play. But maybe a companion could help him be more active.   
What do y’all think? Should we get another dog for a companion or just snuggle him every minute I can? 

Bitty misses his brother…
