When can my 3-week-old puppy wear a collar without stunting growth?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 25 days old | 3.307 lbs

Can I put a collar on our puppy? He's still 3 weeks old. Should I wait til he's older? Will putting a collar around a pup's neck hinder his/her overall growth?

You can place one on him now for a few minutes to begin the acclimmation process. Gradually increase the amount of time he is wearing it. Make sure it is not too tight. No, it will not hinder his growth.
