I'm not sure either. My husband talked to a gentlemen once that was a trucker making a delivery where he works at. Anyway the reason why he talked to him my husband walked outside and saw a yorkie running around so, he went over to talk to the gentleman and he was telling my husband that his dog had to have surgery because he jumped off of a piece of furniture and landing the wrong way and broke his leg and that as a reslut of him being in shock he turn a silver color from black. |
