Our two boys have more toys than anyone could believe, and they are well and truly spoiled. However, Gus (who is 5) will only play fetch for a small amount of time, and his big brother Tyrone (who just turned 6) will often take his toy away if he delays running to fetch it. Gus also is a determined "chewer", and the few toys he has really loved suffer a fast squeaker demise, thereby losing its appeal.
Since they both like the small latex balls with faces, but they only withstand Gus's chewing for a day or two, I was looking online for a possible similar toy to try. I found a Hartz toy, available at the Amazon link posted, and bought a set of three. OMG...Gus ran back an forth robustly fetching it for 2 HOURS STRAIGHT, and begged for more! This morning he made a beeline to grab one, and played fetch for nearly two more hours. We finally told him "rest time", but his body language says he is ready to go if we are willing. This is an amazing reaction, and we are thrilled to have two boys who are each actively participating in playtime!
