<human>: Can you succinctly summarize the text in 1-3 sentences?

A month ago my SO moved in with me and my two cats, with her small dog - after being together for a year and a half or so.

Things are pretty good, we're both tidy and keep the place well, she is beautiful, funny, and smart, perfect right?  Well, mostly, but one thing that has really been irking me is that while she is in the presence of her small dog about 50% of everything she says is either "baby-talk" to the dog, or narrating on behalf of the dog in what she imagines to be the dog's voice.

When people come over, perhaps a plumber, she seems to do it even more, and it's really cringeworthy, at least to me.

I should add that I don't mind the dog, I personally wouldn't get a dog like it (a dachshund), but he is obedient and tries to do the right thing (especially compared to the typical cat, which I'm used to). He also gets on fairly well with my cat (by dog-cat standards).

Now, I know that it's bad in any relationship to think that you can change someone, and I don't want to make that mistake, but this is just one of those things that I can see continuing to irk me, and I wish I could talk to her about it without offending her.

I also in the grand scheme of problems, this isn't exactly a horrible horrible problem, but it's a problem to me.
<bot>: Should I talk to my SO about the "baby-talk" with her dog?  If so, how can I bring it up in a way that won't offend her?
