Size matters. Which Pets Can Engage with SunGrow’s Pet Treat Ball? We love all pets but size matters. Size is important to provide the right challenge to your pet. SunGrow’s treat ball is designed to give maximum engagement and enrichment to small dogs and small dog breeds (under 22 lbs) like Westies, Mini Poodles, Shibas, Chihuahuas, Maltipoos, and Cockapoos. It’s also perfect for rabbits, hamsters, guinea pigs, and rats. Can This Be Used as a Slow Feeder? Yes. SunGrow’s Treat Ball is perfect for portioning your pet’s food. You can give them smaller feedings and get them exercising by portioning their food to fill the treat ball 2, 3, or 4 times a day. This will also develop good eating habits as it will train your pet to eat smaller meals. Eating too fast can cause all kinds of tummy troubles. SunGrow treat ball ends the gobbling in a way your pet will love. Why Does My Pet Chew Things or Overgroom? We can’t ask your pet but many naughty or excessive behaviors come from boredom. Chew products are important because they soothe and help teeth and gums. SunGrow Pet Treat Ball isn’t a chew item. It challenges and engages your pet. Once your pet sees and smells the treat (or you demonstrate how it works), they’ll be excited to put their foraging skills to the test as they rock the ball and then! They’re rewarded with treats! How fun! SunGrow’s Pet Treat Ball isn’t a chew item, it’s an interactive way that stimulates your pet and gets them exercising, eating properly, and keeps them from chewing the couch.
