    My dog has a severe upset stomach. She 5 months old and She Is a pit bull terrier. She involved in it several times today. It’s mostly just been foamy. I did buy a cheaper bag of dog food Than I normally buy last night because I could not afford the pedigree that I usually feed her. But my other two pups also ate this food and are doing fine. I have seen dogs With parvo before, and this does not seem anything like that, nor does it smell of parvo. Is there anything I can give her for the vomiting an upset stomach.

    Hiya – our cocker spaniel has skin fold dermatitis- we have got the infection down to a tiny area but she has now finished her vetinary meds (we are still treating with fucibet cream and flamazinr cream). Can we use flucloxicillin on her and what dose would it need to be?
    Many thanks, we are trying to avoid further vetinary fees and visits as we are in a very high risk area for covid (Liverpool city region).

      I’m sorry, but I don’t know what pet meds you just finished. Flucloxicillin is a narrow spectrum penicillin which means it may not work on the specific bacteria you are trying to eliminate. One thought is you might ask your vet if there is a human version of the meds you just finished as they can often be much cheaper than the pet version.

    My two pit bulls recently got in a dog fight, the one Pitbull is absolutely fine, but the other one has a really bad right ear, in the process I also got bit I went to the Urgent Care they fixed me up, and prescribed me antibiotics I believe the milligram is 125 my question is can I give some of it to my dog that got hurt, and if so how much, it is a pill not a capsule.

    • isak says:

      Often times, yes, human medicines will work; sometimes no. What is the name of antibiotic that was prescribed for you?

      For the dog with the bad ear, a rinse or compress a couple times a day with a salt water solution (2 teaspoons of table salt per cup of warm water) will help. Salt has natural anti-bacterial properties to cleanse and dry the wound.
