Neutering has never effected my dogs coat, i would go for neutering every timeas long as its not done too early my first dog was done at 9 months i think that was too early it didnt effect his growth but i think it made him a little nervous but we soon got around that. We didnt have our second one done as he wasnt marking, humping or showing any unwanted behaviour but at 6 years he got an enlarged prostate and was extremely ill the vet said it was because of him being intact it was caused by the male hormone being present it all had to be cleared up before the op which took quite a while a lot of pain and discomfort for harvey then he had the op the vet did say without the op he would give him around 18 months before prostate cancer so he had the op and it only came back twice after each time much milder as the hormone was leaving his system. So with my experience of having a dog neutered and having another left intact then i would without a doubt go for the neutering.
