I love Paco collars and every now and then I'm tempted to buy one for Pig, but then I come to my senses and acknowledge the fact that it would sit in a drawer. She already has the perfect collar, so it would be silly to buy more.
I mean really, it's perfect for her:
If we're going to the beach she wears the gundogsupply collar, if we're going anywhere else she wears her flying pig collar and she goes naked all other times.
Bear has a Paco that he almost never wears. I love the collar, but I hate it on him. Well no, I don't even hate it on him, I hate putting any collar on him. His coat is super fragile, so he doesn't wear anything if I can help it.
Badger is on his third tuflex now. The one he's wearing now goes up to 22". Once he outgrows that, the biggest collar gds seems to offer goes up to 27". After that, I'll have to search around. The collars I've found so far in the 30"+ range are either super duper expensive or not all that good looking. I won't get him his Paco/other nice leather collar until he's at least 3+ so I can reasonably say it will fit him for life.
Price wise, the most I've spent on a single collar was $150. I will probably go up to $200-275 for one really nice collar for Badger, but that's mainly because of how big it would have to be.
