Hi Traci,

It could be the beginning of allergies...in fact, it sounds like that is very likely, being that he starts to smell in spring/early summer. I would keep an eye on that, it may get worse every year, and he may start to have other signs of allergies like itchy skin, hair loss, swolen ears. There should be no harm (as long as the shampoo is high quality and maybe hypo-allergetic) to bathe him a few times in the summer alone. It may even feel good and cooling to a dog with that kind of thick coat to have a bath every few weeks or so. Rinse REAL well, just in case he does have allergies. If you do suspect allergies, there are plenty of supplements out there that have been proven to help with allergies. I use 2: Prozyme and Missing Link Plus. My Pugs' allergies went away very rapidly after starting her on them. My other dog does not have any allergies but it's not going to hurt him to take these wonderful supplements. Ask your vet, she or he may have some advise also.

Overall, my suggestions would be: 1)feed a very high quality food (not sure what you feed him now but there's some pretty icky stuff in some cheaper brands of food to watch out for)
2)get him vet checked
3)look into high quality supplements with very good testamonials (sp?). If you wanted more info on Prozyme do a search for "prozyme dog" on your browser.

Hope this was helpful...good luck! By the way, my pug with allergies used to stink REAL bad! This little tiny dog made the entire house smell terrible, but since I started her on the supplements her smell has gone down a HUGE amount! Her face still smells a bit, but I think it's from all those face wrinkles
