Gate needs to keep out baby, let in dog

Pen • 8/17 🌈👧🏼 | 11/19 🌈👦🏼| 👨‍👩‍👧‍👦

I want to keep my pets' water bowl (in the kitchen) away from my baby once she starts crawling, but of course I want my pets to still be able to get at it. I have a very small dog (4 lbs) and a cat. The cat will easily be able to jump up onto the counter and into the kitchen (open concept) but the dog of course can't.

Any tips for a gate (or something else) I can use that'll let my dog through but keep my baby out? Thanks!
