The Pedigree Database: German Shepherd dog

i manage to get the size of my doggie.

but i couldn't get whether to get 3.0mm, 3.5mm or 4.0mm?

can anyone help me pls.

thanks

In my opinion the smaller the better, you can lose a finger in the larger linked collars! 

I like the 3.0 MM on my girls, but the 4.0 IMO looks better on the males. This is just my pesonal preference for how it looks!  I am always paranoid about getting a finger stuck in the big ones though!

I like the 3.0mm also...it looks alot better on my dogs and I have got my finger caught in the 4.0mm...luckily it didnt break my finger..it was sure sore for a while.

i got 22" 3.0mm finally arrived. this can slip thru' my dogs head easy.

this doesnot have martingale so inorder to attach this has to be always in leash, right orelse it will come off? ihope i attach properly.

pls. correct me on this....

thanks
