Dog Collar Sizes By Breed

How to get right size for gentle lead collar?
For a giant breed pup that’s only 6 months? He walks fine by my side he’s just been pulling recently because he’s a teenager now I guess.
Do I measure him and get him the size that fits him and buy him a larger one later or what?
How to measure the dog to get the proper size?
IMHO, you’re better off to get one that fits him now, then step up in size when he’s older. If it’s too big, you run the chance of him slipping it too easily, unless you’re able to cinch it up tightly enough.
I like to back it up with a regular collar, in case the dog manages to back out of it.
