2 Dogs

I have these 2 sibling chihuahua mixes brother and sister who I adore but life is getting too serious for me right now and I just don’t know what to do. I don’t want to drop them off at a center cuz that would just mess me up, ik madacc doesn’t euthanize from what I hear but still being in a cage isn’t great. 25 yrs old and I just don’t know what to do, work is getting busier everyday and there’s so much demand of me. It breaks my heart whenever I go home and they wag their tails because i came home after a 9 hr shift. Im asking for whatever help I can get whether it be advice/tips or anyone that could help me train them because I just don’t have the time. I would like to keep them if I’m being honest but if there is anybody interested im not asking for money, I would just hope you can love them and give them a good life. Im asking for any help
