i wanted to know if a car tyre was o;k for a bull mastiff to play with and bite it,my bullmastiff loves playing and fighting with the tyre i got it hanging on a apple tree.is tyre rubber safe for a dog if he manages to chew some off.

                                                  thank u

If he amanages to chew some of and swallow it no its NOT safe.It can cause blockages and you will end with a very sick dog and huge vets bills
