Gum color tends to be pale pink although some dogs do have black pigment so it's hard to evaluate their hydration status (dehydrated dogs tend to have redder gums).
Dry gums, however, could indicate dehydration even though she's drinking and not vomiting it back up.
No abdominal pain is also a good thing.
There are any number of reasons why a dog could develop these sorts of gi symptoms which range from dietary indiscretion to bacterial or viral infections to IBD to systemic disease to a foreign body...just to name a few examples.
It's possible that the suggestions I'll make below will be enough to get her past this but if she's not responding as expected today and/or she worsens, then a vet visit would be suggested.
1. To help reduce her nausea, I'd give over the counter Pepcid AC at a dose of 1/4th mg per pound of body weight twice a day.
2. Don't even offer her anything to eat for 8-12 hours ; just give everything a chance to settle down.
3. Since she's drinking and not vomiting the water, I'd substitute otc Pedialyte since it contains electrolytes and can help to replace those lost in her stools and when she was vomiting.
4. If her nausea appears controlled, then offer her 1 part boiled, skinless, boneless chicken breast and 4 parts 20-minute boiled white rice but only a small amount at one time. Three to four meals a day are preferable to 1 or 2.
5. Once (if?) her vomiting is controlled and she's not taking any steroids or nsaid medication but her stools continue to be loose, then
Regular Strength Pepto Bismol can be given. The dose would be 1 ml per 10 lbs of body weight 2-3 times a day.
For example, if she weighs 50 lbs, then you would give 5 mls or one teaspoon.
Pepto bismol should not be given to vomiting dogs since it contains salicylates (the active ingredient in Aspirin) which can irritate the stomach.
6. I'd start her on a good quality, canine probiotic such as Forti Flora or Resources Protegrity GI. These products can be extremely useful for gastrointestinal issues (and to help strengthen the immune system as well). They may be available at local pet/grain stores or can be purchased online.
Basically, the vomiting needs to be controlled first and then the looser stool issues can be addressed.
But, again, if she doesn't show signs of improvement, if the stools become really bloody or if she starts to vomit blood or becomes really lethargic and/or refuses to eat, then I wouldn't wait to have her seen.
I hope this helps and that she's feeling better soon. Deb
