Thankyou all for your input and nice compliments, I am going to go with the 5/8, but I am also going to order a couple of 3/8 tiny pairs (so we can try on some pigtails

)
On Copper if the bow is too big he looks silly but I agree with Nancy1999 girls can go alittle bigger, there are so many more options in the 5/8 too

.
But after reading the sites I didn't want to order all these bows and have my little dog with a bow that barely fit between her ears haha

your opinions have really helped me feel good about getting the 5/8
