Do you have a grooming table? If not then I would recommend you did. Best thing I ever bought.
As a pup Riley was the same, I had to treat every time I brushed, he didnt like it, then I got the table and from day 1 he was brilliant.
Even now at nearly 2 years old he is groomed every day for about 15 mins and doesnt require any treats, stands when asked to and he actually enjoys it.
It will get better , I remember him being like this as a pup, now when we come home after a walk he will gladly hold me each paw to be washed/wiped without any hassle.
