After they have reached their growth potential, yes. But not before. They need their hormones to develop correctly.
At 18-24 months he should be good to go.
This!
I have had boxers and English bull dogs in the past. Had two litters from each. Always told the new owners to wait at least a year. 2 be better.
At least one heat for the females and wait to get closer to the second one if you must fix her that soon.
The dogs need their hormones to develop properly.
Ones who have waited their dogs looked great.
The ones who believed their vet, their dog didn’t look the same and had health issues and structure wasn’t the same.
