Loss of pets - Now an only dog

That's a lot of loss for the humans in the house, let alone the poor pup to whom you can't explain things.

I have no experience with multiple dogs, so I can't speak with any authority.

I'll just toss out that our rescue wanted potential adopting families to bring their other dog(s) to the meet-and-greet so that you could see if there were obvious red flags. Would that give you a little peace of mind?

Without going too far into my rescue history lol

Might I suggest checking with a good rescue in your area and signing up to do respite care? It’s a serious need that foster families really really rely on.

Fostering is a big commitment- and you sound like you’ll foster fail quickly (it’s a compliment- I promise!) Respite care would allow you to have some canine visitors and friends for your pup without the commitment of choosing right now to add to the family. There’s the added benefit that their personalities are usually pretty well known (dog friendly..)

I’m so sorry you’ve lost so much sweetness! My family has been losing a whole generation of pets over the last year. It’s soooo hard!

Keep in mind that your dog may not like the new pup right off the bat.  Years ago we fostered-to-adopt dog #2 (1 year old).  Dog #1 (8 yrs old) was pretty mellow, but disliked #2 for the first few days and would bully her (not to the point of harming) and #2 would be submissive.  Then #2 started to stand her ground.  They became best friends.
