How to fill holes in my door frames?!

[markthedoc]

I have recently moved into a new house & I seem to have big chunks missing out of my door frames, as if the previous owner had a big dog with a taste for door frames! The wood has been painted over with gloss but some of the marks are about 4 inches x 3 inches big and about 3/4 inch deep. Would I be able to fill them & then sand em down? Without them being noticable? as I dont really wanna get new frames.
Thanks in advance for your advice

You can get thin timber to put on your door frame but door stop would have to be re-position & door edge planed or chop out the damaged area with a sharp chisel,glue the new timber & pin it temporary.When dry remove the pin & sand/planed.Failing that you can get filler from car accessories such as P38 Filler which come in a big tin.
