Thank you for contacting Pet Coach with your concerns about North! It sounds like she has a few things going on at the moment. The bumps could be from an allergic reaction or a skin infection. This is something I'd have her seen by a vet for, as the cause needs to be diagnosed in order for it to be treated correctly. Give your vet a call in the morning to make an appointment.
As for the diarrhea, it could be caused by intestinal worms, eating something rotten, a sudden change in diet, GI illness, eating something rotten, or a foreign body. Make sure she is up to date on her deworming treatments, giving her one if she is not. I can also give you a home remedy to try to see if that helps. Withhold food for 8-12 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck, I hope this helps!

HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Justice!
I would start her on a bland diet of boiled chicken or hamburger with rice. It could be the puppy food she is eating. You can consider starting a probiotic, I like Purina Fortiflora. If the diarrhea doesn't improve I recommend taking her to the Vet or calling them to see what they recommend.
As for the skin, I recommend shaving the fur away and cleaning and drying the skin well multiple times a day. You can apply a topical antibiotic cream like neosporin twice daily.
I hope this helps and I wish Justice a speedy recovery!
