Using your Alzoo dog collar is easy. First, choose the right size according to your dog's weight. Then, simply put the collar around your dog's neck and adjust it to fit comfortably. It's effective for up to 4 months, but keep an eye on it. If it looks worn out or damaged, replace it. Since it's waterproof, your dog can swim or get caught in the rain without a problem. But after long exposure to water, it's a good idea to dry it off. When storing the collar, keep it in a cool, dry place. Always follow the instructions on the box. And remember, this collar is for dogs only, so keep it away from other pets. If your dog shows any signs of discomfort, remove the collar and consult your vet.
