Would this be insensitive?

I'm putting together a gift for a woman struggling with infertility. I was thinking about having a shirt or water bottle made that says "dog mom" because she has a dog.

Then I started thinking that it could possibly come across as insensitive. I mean, I'm battling infertility and I have dogs and don't see a problem with being called a dog mom. I just want to make sure that's not something that bothers others though.
