Bests & Worsts Reviews from Amazon

I rarely write reviews but I feel compelled to make this information public: I have enjoyed using these to play with my 90 lb German Shepherd during the last year. I don't throw it to fly but toss it like rolling a frisbee, the shepherd fetches it, and we play tug for about 30 seconds before I repeat the process. We do this for 15 minutes in the morning 5 days a week for the last year and we go through one of these Chuckit Flyer Toys every month before the warping of its shape starts to hinder its rolling movement. The first picture is an older disc with the result of 1 month's worth of this activity. However, the Chuck it brand Flyer Toys I recently purchased (I've bought two in the last 14 days) have cracked and splintered minutes into our playtime. The cracking and splintering depicted in the second picture occurred 90 seconds into our playtime. I figured that this just may have been a single bad disc so I went to a local big chain pet store and purchased another. To my dismay, the second one noted in picture 3 cracked and splintered the same way within minutes into our playtime. I examined the discs more carefully, compared them with the old one in the first picture, and it appears they have used a different plastic underneath the flexible soft rubber covering. If you notice with the 1st picture showing the old disc purchased in February 2018, there is no cracking or splintering of the plastic at all. Just teeth marks. Picture 2 shows the disc I purchased recently online and it displays the splintering and cracking most noted. The 3rd picture shows a disc I purchased from the local pet store. What is most disturbing about this behavior is how quickly and how much splintering occurred. I worked as a veterinary tech while at university and have seen what the ingestion of plastic can do to a dog's stomach and intestines. It is my recommendation that this toy is avoided until the manufacturer addresses this issue.
