It's a bacterial imbalance in the digestive tract. Will sometimes test low positive for Parvovirus. It is BACTERIAL. It is NOT a new form of Parvo.

Mode of infection: widely varied, but mostly from contact with urine, feces, something brought in on shoes, etc. Symptoms start 12- 48hrs after initial contact (usually) & spread to other dogs rapidly.

Dogs are alert, hungry, energetic. Normal feces starts with mucus sheath & continues to get progressively softer until it is watery & contains blood. It then becomes explosive. Vomiting may accompany & may or may not also contain blood. Feces have a sweet/flowery aroma along with a "slaughterhouse on a summer day" smell (similar to Parvo diarrhea but
with a floral hint). Feces are *usually* mustard colored. Dogs dehydrate at an astounding rate. Dogs are also at risk of intussusceptions.

What is happening is that there is a bacterial growth in the digestive tract which throws it off balance. The body is trying to counteract this by removing the extra (or offending) bacteria. It seems to do this by trying to remove ALL body fluids as quickly as possible. Death is caused by massive dehydration. This can occur as quickly as 12hrs or continue
for a few days. The younger the dog, the worse it is. Some dogs may never get it, even though they may be kenneled with an afflicted dog. Some dogs also get over this without treatment.

The key is to treat this as fast as possible before the dogs go anorexic AND to treat ALL dogs on the premises (non-afflicted dogs should get ONE capsule). Treatment is 250 mg Cephalexin per 25lbs of body weight.

Pups may get Ceph-drops. This MUST be given orally NOT I/V - it MUST go thru the digestive tract (I don't know WHY it works this way, but it does). If the dog vomits the pill up, just give it again until it stays down. Give another dose approx. 12hrs later. If the dog returns to normal DO NOT medicate again. It's important NOT to run a full 10 day course of this drug as it has (in the past) caused the bacterial balance to go the other way. If needed, give medication for 2 more days, or whenever symptoms reoccur.

If the dogs are massively dehydrated, DO NOT use an IV drip. Their circulatory system will be very depressed & *if* a vein can be found, it may not be able to support an IV. Lactated Ringers Solution SUB-Q is suggested & forcing electrolytes orally. IV rehydration HAS thrown animals into deep shock (see above). Slow rehydration. Slow slow slow.
Just enough to keep them alive until the *bug* is nipped in the bud.

After the diarrhea has stopped, you can cram the dog as full of fluids as you want, just not when it is at its most fragile point.

Anorexic dogs have to be tempted to eat again. Rare, bloody, slightly garlicky & slightly salty beef has worked the best in the past forgetting the appetites working. Start small. You may have to give anorexic dogs Nutri-Cal to get them going again. But after they are cured they *will* begin to eat again.

Do NOT automatically assume Parvo when you see this. Parvo treatments have killed the majority of Crud dogs. If you suspect Parvo, try the Cephalexin 1st, if it doesn't work, THEN assume Parvo. Do NOT use Amoxicillin.

Keflex has worked in the past. Dogs should show improvement within hours of treatment.
