Change of coat colour

Question
Hi my 7 month old male bull mastiff has small patches on his coat that seem to be changing colour..is this normal?  He is fawn and was neutered a month ago.  Cheers

Answer
Nobody knows everything, and the most reliable answers come from those that know and admit their limits.  Only somebody specifically with Bull Mastiff experience could say for sure.  I do know Shepherds and some other breeds do change color as they mature.  You either need to find somebody with Bull Mastiff experience or talk to your vet.  You might go to www.akc.org and see what they have in the breed description or check some of their limits.
