If your dog is pregnant and itchy, there are a few things you can do to help. First, increase the frequency of brushing and bathing. This will help to remove any irritants on the skin and will also stimulate blood flow, which can help to ease itching. You can also give your dog an oatmeal bath, which can be helpful in relieving itchiness. Finally, make sure that your dog is getting enough essential fatty acids in her diet, as these can help to reduce inflammation and itching.
