One more little trick that helped my old dog. A drop of lavender oil near where he sleeps has been helpful. Not a lot only a drop. I also massage him occasionally and he sleeps like a baby.
If you know of a trusted vet and she's still having problems after all you have tried then IMO yes.
The scratching could possibly be a nervous or an allergy issues, as already said.
If it's a nervous problem that could have transpired from being the runt .
My dog has always been nervous...
Well a vet I have listened to for a couple of years on youtube would suggest that. Just a little. The probiotic should help settle the tummy but make sure she's allowed to 💩. This may make her want to go out for Potty more, which imo, would be a good thing 😀
How about a little wash with some vinegar and baking soda to rinse off. The vinegar is acidic, fleas hate that and the baking soda dries and burns them. Plus both helps with itching. For us to. I also use this regularly on my dog and cat. But wash them with an organic liquid soap then rub in...
In the meantime, do you have any pumpkin seeds? I've heard if they are chopped small and put into their food it may help for a short time. As it's a young puppy I wouldn't suggest garlic and cloves squashed up into the food. I do this on occasions for my old dog.
