Dog Fur and skin problems  

Has your dog gotten into well he was outside?? I might be from something he got into and is having a reaction to it. You can try going on google and look up Pets Health Care. But truthfully I wouldn't wait, I would take him to the Vet and see what he has to say as I'm sure it can so many things...

Hard to tell without seeing it, or a better description of it. Could be fleas and the marks you're seeing are from him scratching. Or could be an allergic reaction. Check around the yard, was he laying on something different? Did you recently change his diet? If not, I wouldn't switch his food. Is he eating and drinking normally? Acting normal? I'd call the vet to be on the safe side.

Dogs generally shed once or twice a year and at that time their fur becomes very thin. This is normal and nothing to worry about. Just thier way of making place for new fur. The rash could be caused by an alergic reaction or if he came in contact with a dog with a contagious rash. Try bathing him with cool water and some antiseptic. It will cool his skin. I doubt that the food would suddenly affect him by giving him a rash

I'm glad you tried the food change, and are now calling a vet. Sounds bad. Maybe mange or an allergy or worse. Keep us posted. Good luck dear.

I don't think you're supposed to bathe a dog once a week. If you wash them too much, like people, it strips the natural oils out of their skin/hair-causing dry itchy skin. That may be what the problem is. Cut back on the baths and see if that helps any!!

sis,

have your dog checked by a vet immediately. it's hard to assume on things that happened to our dog since they can't talk to us. we don't know what's going on inside them. so better, consult your vet asap.

my dog also have some sort of allergies with chicken before, his skin becomes reddish and scratches almost all the time... he had even less time to get sleep. a day after, i called up my vet and when she went to my house, my vet immediately told me to confined my dog, coz the symptoms are so true and evident for mange. :(
my dog is confined for 2 weeks, it's just so nice i have known my vet so well to feel what i feel for my most precious dog.

my dog also got some allergies with cement, and my vet manage to cure it...

shedding is normal for all dogs, this is their way of changing old fur to new ones. dogs also shed especially for hot days... they also shed in their heat period.

my best guess would be one of two things. Either one your dog has developed a allergy, or two, they might have hot spots. Either one can be easy diagnosed by your vet, and is very easy to take care of. It may be just a matter of getting a lotion or ointment that cost only a couple of dollars to simply just changing his food. Either way I would contact your vet just to be on the safe side.
