Tennessee, I know you mean well. But I find that most of the time once people make the decision that the dog needs a new home, the dog is better off in a new home. Beyond an effort to describe experience with large dogs and kids, we really should focus on helping the lady re-home the dog.
Because another sad thing is that, once the decision is made to re-home the dog, sometimes people kind of divorce themselves from the dog, probably in some unconscious attempt to protect themselves emotionally. When this happens, dogs can wind up in shelters or even abandoned.
Who knows what I would do if i was pregnant with twins and had a baby already. If, my momma-bear hormones kicked in, anything that might harm my babies would have to go.
A lot of times twins are born early and under-weight. Sometimes they have to be hospitalized for a while. When babies are in the NICU, mothers spend almost all their waking hours there.
We don't know what the situation is, or what it is going to be, making tough decisions now, so that she doesn't have to throw the dog on Craig's list or dump it in a shelter is probably a mature and responsible thing to do.
The dog will get over the change in ownership faster than the owner.
There are plenty of crappy reasons to rehome a dog or to dump a dog. This isn't one of them.
We always say, never leave a dog unsupervised with a child. Well that may be well and good if you have one. You can put the dog in a crate when you use the bathroom, or if you are cooking dinner. The rest of the time you are chasing your baby 24/7 and it is never "alone with the dog." But if you have three babies all running in different directions, the poor dog would have to be crated constantly.
Really, I can only judge for myself what is going to be too much for me. None of us can judge for others what is too much for them.
