Article in English: When dealing with a pregnant dog, it's even more important than usual to make sure she stays calm. Her extra weight might make her harder to hold down if she starts to struggle. Pet her in long strokes and speak to her in a soft voice. Do everything you can to relax her.  If you think she might try to escape, get another person to help you. More hands means more petting! If your dog is afraid of baths, don’t force her. Just brush through her coat instead, trying to get as much dirt off the fur as you can. It will be easier on you both. Allow wet mud to dry into dirt before brushing her. Even if you’re feeling worried about bathing her because she's pregnant, don't let her pick up on your anxiety. Act like it's a completely normal bath, and don't change the routine at all. For example, if you usually lift your dog into the bathtub, give her the bath in her normal place. Don't decide to spray her with a hose outside instead because you're afraid of lifting her. Keep treats on hand to reward her for calm behavior or coax her into the tub. You'll also need shampoo for the bath and several towels to dry her off before letting her loose in your home. You can put one of the towels on the edge of the tub to stop some of the water from splashing onto the floor at your feet.  Use a nice, mild oatmeal shampoo for dogs that won't irritate her skin. You're going to get wet, too, so dress down in clothes you don't mind getting dirty. You know from experience that bathtubs can get slippery when you add water and soap to the mix. A non-slip mat will help your dog keep her footing while she's getting her bath. You can find non-slip mats in any department store or online.
