Gizmo's testicles didnt drop until 7 months!! The vet tried to talk me into having him do abdominal surgery. I said no way!! I'm glad i did because Gizmo would of been too tiny to have the surgery done earlier and wayyyyy more $$$$$!!!! Im getting him fixed the first week of march! Im so happy i waited he was just a late bloomer
Good luck and go with your instincts!
