Those seeem big for westies, must be well fed and healthy! Is there a miniature breed, because I've seen some about six to 10 pounds but maybe they are just babies. I know with my little dogs, that were smaller than kittens, I had to really work to keep them warm, sitting in the chair with them wrapped in a towel and blanket, using heating pad at times and also to watch out for hypoglycemia, which small dogs like chihuahua and other breeds are prone to. If the dogs shiver, it may be from low blood sugar, so if heat doesn't help, I gave mine suger water in a bottle. I've been told that you really need to get it to them fast because they can go downhill and die quickly from hypoglycemia. My older female has it and she just gets a peanut butter cracker when it starts or some other non chocolate sweet treat. I hope westies don't have that.
My dog gave birth in her cage, which is large for her, because otherwise she probably would have had birth under my bed or on top of it. When I saw her in labor, she went into the cage and had them and I helped her. The puppies stayed in the crate from the day they were born, so it was ideal, thinking of it as a safe place and home. Also, we have cats too and I didn't know how they would react to newborn puppies that were so tiny. I had to put cardbord around the sides of the cage because the puppies were so little they could crawl through the bars. I believe in cage training. My older dog didn't really need it, she was really smart and wanted to be human so much that she just got it together in three days. My male puppy, Carlito, will still sneak off if he really has to go and will go in the house. If left alone, I don't trust him not to tear up stuff or have an accident so he stays in his cage when I go to the store. It seems each dog is different, but cages really make life easier and they shouldn't be punishment, but a safe place where they get rewarded. There is always a bowl of food in my dogs cage so he can eat incase the mama dog is not letting him get his fair share.
