You probably introduced it to him incorrectly. Try playing with him in the bathtub while it's dry. Comfort your dog and play with her inside of it. He will soon like the bathtub. Next, put an inch of water into the tub. Get into a swimsuit and start playing exactly like how you were before except with a little bit of water. Do this for two weeks and then try bathing your dog again.

Don't overdo bathing. Once every 6 to 8 weeks is typically enough. Professional grooming services are recommended once every 4 to 6 weeks for long haired breeds. Bathing too often can dry out the skin by removing the natural oils. Waterless shampoo can be used between baths to clean feet and other areas. Spot spray directly and sponge off with a damp sponge. Use a hypoallergenic or mild oatmeal shampoo designed for dogs for general bathing. If your pet has a particular skin condition, try hypoallergenic scent free shampoo before the vet. If the condition persists, a medicated shampoo from your veterinarian may be in order. Consult your veterinarian if there are concerns about your pet’s skin.
Please note that regardless of pet type, we always put safety first. Sometimes pets can stress in new situations. If we feel your pet is too stressed or showing any potential health concern, we may opt to conclude the grooming appointment in order to do what's best for them. Your stylist can help recommend a grooming service for a smooth introduction, such as a Mini Make-Rover. For any potential health concern your stylist will refer you to your veterinarian.
