I'm looking for dog GPS trackers and would appreciate more info on your available models. Specifically, I'm interested in features like real-time location tracking, battery life, waterproof ratings, and any health monitoring capabilities you might have. It would also be great to know about the range and accuracy of the GPS, as well as integration options with mobile apps. Additionally, please include details about minimum order quantities, pricing, and lead times for delivery. If you have any promotional materials or user reviews, that would help me understand your products better. Looking forward to your response!
