just checked the breed standard. Pleas do not let the groomer trim his feet ad the standard calls for:
Feet
Fine, fairly long, hare-like. Tufts of hair between toes extending far beyond them
I think you are best not to trim at all only have him bathed and combed.
For coat it says:
Coat
Abundant, flowing but without undercoat; long fine silky, falling flat on back and sides; profuse frill on chest; short and close on skull, muzzle and front parts of legs. Rear of forelegs to pasterns, tail and thighs covered with long hair.
