ds2, that tells me everything. small tail=NOT a red fox, and therefor, not a silver. red fox have HUGE fluffy tails that look almost as big as their body. It was probably a grey. UNLESS the silver (red) had mange and his tail was eaten up... a healthy fox tail should be huge!
Here's a pic of a grey fox...notice it looks speckled black/silver look? I'd bet this is what it is.
Grey fox, on average are just a couple, as in 2pounds larger, but could've been that years pup, so a little smaller. Grey fox have a fairly fluffy tail, bigger than the kit fox, but still smaller than the red..and the red would've had a bright white tip.
If you take a 10 lb red, and a 10 lb grey, and put them side by side, the red will look bigger. The reason is because red fox are all fluff, their hair gets really long and fluffy making an average one look about 20lbs, though they rarely go 13. Grey fox live more in the (relative)south and have a thinner fur that lays down more, so most the bulk you see on them is actually body. This may be anotehr reason it looked smaller than reds you've seen.
