well i appreciate the input, but honestly the collar doesnt seem to be bothering him at all (and i have it so i can stick two fingers in between teh throat and the dollar itself), this is the primarily the whole reason i asked if anyone used a leather collar, because of the stiffness in teh leather (and it will soften over time but not too much) it holds its shape really well and doesnt have any direct contact with the throat. I was just like most of you at one time and didnt want a collar on him either, but my fears have gotten the better of me, and this is a collar that really seems to work for him.
As for youre question
gypsy rose..... toby is 5 months old (and 8 lbs

) he got the microchip when he was neutered, the company for the chip is called AVID (i dont know if there is more than one company who produces these chips) the "ID TAG" that they gave us is plastic with his number written on it and it says "If i am lost contact AVID at such and such number" his ID number is underneath that..... his ID number is on both sides acttually.... i like it but plastic is kinda not durable ya know what i mean ????? I might if his ID tag ever breaks just copy exactly what that says onto a metal tag....
