We've been noticing lighter patches on Casey's liver patches, upon closer inspection the hair is clearly thinning in these areas. It was not like this before. Other than that, his coat appears healthy and shiny. He has little hair loss overall, and does not appear to be shedding more than what he normally does.
I'm wondering if this is normal? Or it could be caused by the dry weather? Or from his neutering last year (he does seem to be laying around a little bit more.)
My girlfriend's 8yo GSP has the same thing (in the same spot). They have checked her for everything and changed her diet and no change. Hopefully you can sort this out for Casey.
