This is a memory (video) that I pulled up on Facebook. I point it out as the dogs do have fun on the pool cover but that dog sporting a short coat that looks almost grey and white is Logan. In short hair he looks like that but in longer hair you can see he is a beautiful sable. Short hair often gives an appearance of lighter and of course you cut off the tipping never to come back again. Logan now is sporting a long coat and you can see his sable is evident.
Sables do go lighter and darker throughout their lives. Brindles do too but have an irregular colour coat distribution. At times it is hard to distinguish between a sable and a brindle. Both can sport black masks that fade or get retained.
Roxie almost went a pure cream colour at one point and now she is back to being an apricot in appearance. If you look real close you see many shades in her coat. Adele is similar. Their mother was the same.
White coats will always remain white with the exception of ticking (black bleeding through). Dark coats can change. Blacks can have an appearance of grey or brown. You can get colours bleeding through and therefore you get to see coat changes.
I find the Havanese coat fascinating. Kat was a black and white as a puppy. He is now a silver and white. The photo above is Kat when I was maintaining him for the show ring. Now he is older. He plays and I am not so particular about him being perfectly groomed though he gets a bath every 2 weeks. Nathan always likes to show him off just before I bathe him or brush him or so it feels like.
Logan is not our breeding but he is related to our lines.
His father was Abigail's brother. It means both Roxie and Adele, Panda and Ella are related in various ways to him on one side. The other side was from a Cuban gal that our friend Yvonne owned called Lola.
This photo here is Logan as a pup. It appears he was a brown sable. He transformed into an apricot sable. He still has brown in his coat. It just means he has more apricot than brown so the apricot is more apparent.
Sables are a multitude of colours.
