And... of course, make sure dogs are vaxxed, well behaved and groomed. Other than that, let the love flow
Statistically speaking dogs mouths are cleaner than humans. But I only stop my dog when she's doing it excitedly because sometimes she bonks him with her nose and he falls back
Honestly, no matter if dogs mouths are clean or not (I’m a dog person, so I’m def pro lick on my own face) it’s your call not theirs and they should help enforce whatever that is since their visiting you. We keep a healthy space between our pup and baby because he wants to grab at her, so it’s safer for both of them.
If your baby goes to daycare, mall, library, grocery shop, doctor's office, airport, anywhere... it's not the bacteria on dogs' mouths that will cause a malicious illness. I like to remember that babies are quite resilient - and I caught my 10mo "drinking" from the dogs bowl one too many times 😅
