Our year old puppy loves this! We use it indoors and outdoors. Only complaint is you can’t load all the balls in at once, otherwise they all get shot out. Wish there was a time delay so we could load multiple balls at once.

Noticeable difference in energy—my senior Lab loves the chewy texture. Highly recommend!

I've tried several ball throwers for my two Boxers, but none compare to the Ronzeil Large Automatic Ball Thrower. First, it's incredibly durable: Boxers can be quite rough when playing, but this thrower is made of thick, sturdy plastic and can withstand their chewing and impacts. Second, it's incredibly convenient: it holds five balls at a time—no more stopping to refill every two minutes. Third, its training value: I use it to train my dogs to catch—after some training, my Boxers have learned to put the balls back in the thrower themselves, which has fostered a sense of responsibility. Now my dogs are more energetic and less prone to boredom and misbehavior. This is more than just a toy—it's a practical and durable tool that makes life easier for both me and my dogs. I simply can't imagine life without it!

Raising a Mastiff puppy means prioritizing its healthy growth, especially muscle development, as large breeds are prone to joint problems if they gain weight too quickly. I started feeding my six-month-old puppy Ronzeil muscle-building chewables, and it worked wonderfully. The chicken flavor was a hit—he ate it every morning, and it became a reward during training. This balanced formula contains a moderate amount of wild Alaskan salmon oil and plenty of Omega-3 fatty acids, promoting lean muscle growth without over-muscle gain, which my vet said is crucial for his joint health. After three months, his muscle definition was very pronounced: broad chest, strong limbs, and he moved with the grace of a much older dog. I love how easily the chewables are digestible—they don't upset his stomach even when his appetite increases—and the ingredients are transparent (no strange additives I don't recognize). Even better, the dosage is adjustable, so I can increase the amount I give him based on his growth. This supplement is a lifesaver for dog owners looking to help their large breed puppies grow healthily. It's safe, effective, and meets the unique growth needs of large breeds.

This is the best thing I've ever bought for my energetic Labrador! The non-electric design allows him to control the pace himself—no more annoying motor noise. Now he runs for 20 minutes every morning, and his excessive indoor activity has noticeably decreased. Excellent value for money!

Perfect starter set for agility training. Lightweight but tough enough for my energetic Rottweiler.

I have two dogs: a 3-year-old Golden Retriever named "Cola" and a 2-year-old French Bulldog named "Potato." One is energetic and loves to run, while the other is less active but needs to be kept fit for weight control. Before, walking the dogs required two separate sessions: a 30-minute run with Cola followed by a 20-minute walk with Potato. This took an hour every day, and I was exhausted. Then I got a Ronzeil non-electric treadmill, which allows me to manage the exercise needs of both dogs all by myself – it's so convenient! This treadmill has a strong weight capacity; even with both dogs weighing a combined 120 pounds, it runs very stably. The running belt is wide enough that they don't bump into each other. Cola loves to run, and 15 minutes of running is enough to burn off excess energy. Potato, being less active, is encouraged to walk for 10 minutes with treats, which helps control his weight without tiring him out. The advantage of the non-electric design is that you can "run whenever you want and stop whenever you want." Cola gets tired and automatically gets off to let Potato take over, without me having to adjust the speed or turn it on/off. The treadmill frame is incredibly durable; even when Cola excitedly lunges at the running belt, it remains perfectly still and undamaged. Cleaning is also a breeze; the running belt is made of a non-slip material, and even when Potato drools on it, a quick wipe with a tissue is all it takes. For multi-dog households, this treadmill saves time and effort, ensuring both dogs get adequate exercise—it's truly incredibly practical!

Very good way to exercise a high energy dog on a rainy day! Just make sure to condition them to it properly and don’t use these in replacement of regular enrichment - but the quality is good and this has lasted us quite a while!

Picky Rottweiler gobbles these up! Noticeable difference in 3 weeks—less limping after walks, more energy during play. Chicken flavor is irresistible, and the soft chew texture is perfect for his jaws.

As someone who loves training dogs but lacks the energy to fetch balls all day, the Ronzeil automatic ball-throwing machine has become an essential tool for me. I have a Border Collie and a Belgian Malinois—both very intelligent and energetic—and this machine keeps them both mentally and physically active. The machine is incredibly sturdy and durable—my Malinois has knocked it over several times, but it has never broken. The battery life is also impressive—one charge lasts for several games. My dogs get excited as soon as the machine starts up, and it's wonderful to see them happier and more relaxed after each session. If you want to make training your medium or large dog both fun and effective, this machine is definitely worth the investment.
