Rufus has started to scratch and itch a lot in the last couple of weeks. He is also shedding a lot of hair and producing dandruff. Nothing has changed in his enviornment or his diet. Ren's reccomended adding fish oil to his dinner to help this however now he's got the runs!

Any Ideas? Is this normal?

I should mention also he has had his fleas and heartworm doseage beggining of June.

Thanks.
