Grooming is important for both the health of your pet and the bond you share. Grooming your puppy is a nice way to spend quality time together while also allowing you to monitor your dog's health by checking for cuts, bumps, tenderness, etc.
The bathing products available for dogs today are almost as numerous as those for us humans, and they're much better suited to a dog's skin type than human shampoos. Choose a special dog shampoo that's best suited to your puppy's hair type and take extra care not to get any shampoo in his eyes when washing him.
You may want to invest in a non-slip rubber mat and place it on the bottom of the bathtub to give your puppy confidence during bath time. It's scary for a puppy to slide around on a slippery surface and this may increase his anxiety around bath time.
