Yes, there is some truth to this.
It falls in line with men who have pics of their kids on dating apps. They are clearly trying to tell people that they come with the kid. If you want to be with them, you also have to be ready to accept and love their kids.
It’s the same with the dog pics. If you want to be with them, you have to be ready to accept and love their dog.
What do guys often do with their dogs?
They go out on walks or jogs with them. Play catch with them. Go camping with them. Take them on road trips. The dog is a big part of their lives.
Guys who are looking to settle down engage in these activities often and if they have pics of their dog on a dating app, they are hoping that the girl partakes in such activities as well.
A guy who is only looking to hook up isn’t looking to have a girl bond with his dog, which would require that she partake in various activities with him and the dog. He is just looking to get laid.
