dolmation

I have a sub adult Dolmation crestie which has black spots but I have noticed lately small red dots coming through, just wondering if anybody else has seen this befor if not what it could be?!

Hi, My name is Dipstick, you can change my name if you want to...but I was named after one of the dogs in 101 dolmations as I am a Tri Standard Dolmation Spotted Rex, I am a little girl and very friendly, I love cuddles and kisses and running round in the garden, I am 8 weeks old next Thursday...
