Rash on Belly..What should I treat with?

Hello!  I'm afraid that that depends what's causing the rash.  If it's fleas, you'll need to use a veterinary-recommended flea treatment at the correct dose and frequency; if it's mites or flies, there may be a different anti-parasitic treatment required.   If fungal or bacterial infection is present, for example, then this will obviously need to be treated and if an allergy is likely to be involved, then steps may be started to work out what the dog is allergic to.  And so on. Depending on how much - if at all - the dog is itching, appropriate anti-itch treatments may be recommended because scratching can make a lesion much worse.  Not all skin problems itch and this can be a vital price of information for your vet when it comes to diagnosis. Skin problems can be frustrating: they tend to recurr and tend to take a certain amount of time and effort to diagnose, but it's absolutely worth visiting your vet because many of them are chronic i.e. may continue eg throughout the pets' life - so getting a diagnosis, which will enable you to know what it to do when it flares up, or even to avoid the flare, is extremely important.  Furthermore, a very few are more sinister and they need to be caught and diagnosed. Looking forward to hearing how you get on.

Its not itchy/ its been there awhile now thought it could of been poison ivy. Will be taking her to the vet Monday when they open.

Best of luck and do let us know how you get on   Obviously, if your pet has or develops other symptoms or you have concerns about poisoning etc, your vet will have someone on call over the weekend who could triage the case in case you ought to be seen earlier.

Vet said it was a bacterial infection gave us a shampoo/pills "Douxo Chlorhexdine Shampoo" to use twice a week..leave in 5-10 mins then rinse and "Simplicef" pills once a day with food for 10 days.
