Just heard from Sumo's human about his new collar. Sounds like he's enjoying it!
"Just wanted to say thank you so much for making Sumo a new collar. It looks awesome and he no longer needs to feel like he's being choked by a collar that's too small! It was hard to find something that fit a 200+ lb dog with a 28" neck. I am so impressed with this! Thank you again so much. I will recommend you to everyone I know!"
