Sounds like you may need to change a few things, working slowly and go from there.
#1 - Marking ~ This can easily be helped/avoided by getting him neutered. You would be doing Him and Your Family a wonderful thing by getting him neutered.
#2 - Food ~ As stated above Iams really isn't the greatest food. There are so many 'other' foods that are better for him and they don't cost much more. Some ex: Wellness, Natural Balance, Canidae, Merrick, Solid Gold
#3 - Shampoo ~ Minksheen (online ordering) has a really nice smell. It has antibacterial features as well as aroma that is suppose to repel insects. It makes there hair really soft and smelling fresh. (no need for conditioner either, as it has it in the mixture) |
