They're not! They're good.

I particularly like Carina and Dilita.

Keep going, keep sketching. Try using the pastel in different ways, experiment with it.

You should also try sketching individual parts of your dogs (or anything else you wish to draw). Even just sketching the general shape of the dogs in a pose helps.
Have you drawn with any other media before? Pencil sketching can be a little easier than using pastels.
And on a different note...when are we going to see a picture thread of your dogs?

Hehehehe!
