Is it okay to bathe my dog once a week?

Some dogs benefit from a more frequent bathing schedule, as often as weekly, especially if there's exposed to a lot of environmental allergens and get dirty beyond just a good brushing and pet wipes. The next time you talk with your vet, it would be good to discuss.

Depending on if he is a long hair or short hair dog because long hair dogs will smell like wet dogs when wet making any smell worst. I try to wash my dogs as little as possible and use only water as much as possible. If not, a soft non-scented dog shampoo will do, just make sure to dry your dog as best as you can.
