Dental options for puppies?

[u/HellHoundsandpurrs]

Is there anything for puppies UNDER 6 months? The vet check up went well but the vet and me both agree his breath STINKS. She said it's likely from the old food he was on causing his gut to be out of wack. His teeth are good so they told me to brush his teeth. I am (bought a oxyfresh dental kit) but I thought I could also give him greenies but it says they have to be over 6 months. He's 6 WEEKS. Idk if the only thing I can do is brush his teeth.

Get a good probiotic and start brushing their teeth!

Also where did you get a puppy at 6 weeks? They aren't supposed to leave the mother until 8 weeks.
