I find my pitbull always smells so clean and fresh, shes a female but i do notice that if i forget to clean her ears, holy, the smell is so bad, i asked my vet and they said its normal and just to keep her ears clean. I’ve owned about 7 or 8 pitties and for some reason i find they all have that pitbull smell to them, have you checked to see if her skin looks normal? pitbulls are definatly prone to skin condition. I have a bigger dog and she smells absolutely horrible, but thats only when shes shedding and her skin gets really irratated by all the oils. Hope you find a solution to your problem!
