I was pondering for when it will get dark and my dog isn’t close, or if he will get further away and I need to find him. While each collar held up nicely enough throughout our evaluate period, I really have doubts that they’ll last through everyday put on. Dogs are capable of dispensing an unbelievable quantity of put on and tear on their collars, from scraping themselves towards bushes and shrubs to scratching at their neck with their hind leg. While all collars we reviewed claimed to be weatherproof, just a few had been waterproof. So to check these claims, I took each collar out in a snowfall and a light rain. The rechargeable LED collars were charged for 12 hours prior to use, imitating an overnight cost.
