Even if you could rehome a few of them it would help. You're so right...dogs tie you down. You do need to spend time with your husband taking trips, and it would be SO much easier with just a couple of dogs. Don't feel guilty about it! I'm sure you could find wonderful homes for them, where they could get lots of love and attention. Unfortunately, none of us are getting any younger
We have a great dane and a mi-ki. We can leave the big guy in the back yard, and my brother checks on him...he lives across the street. We take little Layni with us, or my dear friend keeps her for me. It's much easier to make arrangements for just the 2 of them.
