Need advice, dog lovers

I’ve been fostering a sweet Chihuahua dog since May and eventually decided to keep him. However, life has changed a lot recently—I just had a newborn who needs so much of my attention, and in about three months, I’ll be returning to work, running my own business with 12-hour shifts.

This dog, in particular, requires a lot of time and care. He’s 10 years old, very attached, and has severe abandonment issues after being dumped at a shelter by his previous owners. It breaks my heart because he deserves so much love and attention.

I recently found a wonderful 73-year-old lady who absolutely adores him. She’s been caring for him for about a week now, giving him all the love, time, and attention he needs. I know he’s in great hands, but I can’t shake the guilt. I keep thinking about our walks and trips to the beach, and I miss him so much. She did mention her age and how he can live a very long time and while she’s healthy, I don’t know how to bring up the conversation about what would happen if she could no longer care for him or if she were to pass away. I want to make it clear that he will never go to a shelter or just anyone’s home—I would require that he comes back to me.

I shared my concerns with her, and she assured me that I can take him back anytime if I decide to. But looking at the long term, I know I won’t be able to give him the same level of attention that she can.

To my fellow dog lovers, do you think it’s better to let him stay with someone who can give him the love and care he needs, even if it means letting go? Or should I bring him back and do my best to make it work? I’d love to hear your thoughts. ❤️
