Sick Baby

Without knowing more the best advice I can give is to see a vet - as Ottoluv suggested.

Her age, her status on vaccines, and whether or not she has been wormed are all important factors.  However, this could be as simple as nerves or needing to feed her more frequently.  If the vomit is green or yellowish-green, it could just be bile and the result of having the stomach empty for too long.  Lots of dogs even need a snack at bedtime to keep from vomiting bile.

Pick up some Nutri-Cal at a pet store and some plain Pedialyte at a grocery store.  Nutri-Cal is a high density nutrient paste and Pedialyte is designed to restore electrolytes.  If the pup's blood sugar drops too low (pup is lethargic), put a small amount of Nutri--Cal between the teeth and the cheek.  If there is very much vomiting or diarrhea, use the Pedialyte.

You can get lots of medical info on dogs from www.peteducation.com, so remember that site.  I suggest you look up Parvo, Distemper, and Coccidia.  Also read their instructions (link) on how to administer liquid medications.

In addition to Nutri-Cal and Pedialyte, your doggie first aid kit should include:

Benadryl for allergic reactions - The dosage is 1-2mg per lb of body weight 2-4 times/day.  The tablets are 25mg and you need 1.5-3mg right now, so you will have to get the liquid and a children's dosage syringe (or a regular syringe with the needle removed).  Every time you get the liquid, check to be sure that it is not "sugar free" (has an artifical sweetner).  Xylitol or Sorbitol could prove fatal to your pup.

Hydrogen peroxide to induce vomiting (3% solution) - The dosage is 1 tsp per 15 lbs every 15 minutes until vomiting is induced.  With such a tiny dog you will need a dosage syringe for this one, too.

Kwik Stop powder (pet store) - This powder will help to stop broken nails from bleeding. 

CAUTION:  Xylitol is a very common sweetner in sugar-free products.  As little as one breath mint, one piece of candy, or one piece of gum containing Xylitol could kill a very small dog.  If you even suspect your tiny pet has consumed Xylitol, induce vomiting and head for the vet immediately.   DO NOT WAIT FOR SYMPTOMS.  Xylitol causes a severe blood sugar drop in dogs within minutes and damages their livers.

Treat Xylitol products as cautiously as you would rat poison.

 Janet, you rock!  I don't have a dog first-aid kit; just get what I need when I need it.  I'll put the above on my shopping list immediately.

I did know that sugarless gum could be dangerous, but not how dangerous.  Scary, indeed, especially as Ems has a knack for finding gum in trash cans, etc.  Ick.

I would assume that most of the Xylitol is gone from used gum. 

NOTE:  Larger dogs can consume more Xylitol without experiencing a significant drop in blood sugar; however, that doesn't mean that there was no liver damage.  Large dogs given small amounts of Xylitol on a regular basis could wind up with liver failure.

I was extremely emphatic about Xylitol for the OP because no amount of Xylitol is safe for a 1.5 lb pup.

Every doggie first aid kit needs Benadryl (not the "sugar free" liquid version), hydrogen peroxide (or Syrup of Ipecac), and Kwik Stop at the very least.  Nutri-Cal (nutrition) and Pedialyte (dehydration) are needed for frail/sick pups and dogs.

Other items that should be considered for your first aid kit are

• items that must be the correct size for your dog
• items that must be ordered
• items that are not available when you are away from a city (water?)
• items that are needed quickly if the dog is injured

If your dog were hit by a car, could you

• provide light if needed (flashlight) 
• keep a half-conscious dog from biting in pain (gloves, wire muzzle)
• apply a tourniquet
• immobilize a limb (splint the way you find it and do not attempt to straighten)
• clean and bandage a wound (hard to clean if no water is available)
• carry the dog to your car for a trip to the vet
• stop him from bothering his stitches (Bite Not Collar)

If you went on a hike, could you take care of

• a cut paw (skin glue, boots, etc)
• a splinter (tweezers)
• a tick

• porcupine quills (long nose pliers)

If your dog were sprayed with pepper spray, do you have the right supplies to relieve the pain?
