Anyone ever have a pup go from a perfect scissor bite to a very slight overbite at 5.5 months old? This is my pick bitch and I have been watching her bite now for a couple of weeks.. It's not getting worse, but is staying the same... It is ever so slight. When you look at her from the front it looks scissor and pretty tight. I doubt I could even fit a match stick in there,, But you can see the canines are in a tad too far on her profile.
Her littermate does have a significant overbite and has all along. All others in the litter are fine. Mom's previous litters all had scissor bites.
I am hoping it's a growth spurt and soon she will be back to normal..

Yes. At this age they are growing, especially their heads. I would not give up just yet. Had the same thing happen and in the end of the growing spurt the pup was scissor!

Good luck!
