6 month old puppy TMI

Karen

Is this much plaque normal for a 6 month old puppy ? His breath also smells pretty bad ! I don’t remember my other dog developing plaque on her teeth or bad odor until recently that she just turned 3yrs old and even then her breath isn’t as bad as the puppy’s 🤢. Any tips to help deal with it ? He hates getting his teeth brushed I literally have to pin him down and it just stresses both of us out 🙄
