It’s just my opinion but I would keep them both and have sis spayed. I have 3 all females and they are a lot of company for us so I know you would miss them. It’s ok to make a plan for someone to take care of them when you are gone but you are providing them with a loving home and your company.

Good afternoon @kskill39. Oh dear, this is a very touchy subject with me. i am a Cavalier King Charles Spaniel fan and have had three of them, one being a rescue. I made a commitment to myself that I would not have a dog that outlived me. Cavaliers are such companion dogs. She would miss me and I don't want that to happen. So, I am the one missing my Roxie and Reggie, and Kala.

It may make things worse, however, I can't help belonging to several Cav groups on Facebook. My morning wake up always includes a check on new images in the groups. Maybe I could just be a caregiver for others when they need help with their Cav. Would that even be harder yet to manage? And I too just loved them. They went into my business every day to greet customers. On Saturdays, they put on a dog show at 2:30. I had to limit it because people were coming in all during the day to see their tricks. They got a bit tired of performing.

I will soon be 80. If I did get another one, I would look for one that was being re-homed. I know my breeder does that for folks.

May your memories bring you joy.
Chris
