Can Miconazole cream treat fungal infections between dog paws?

Miconazole is an antifungal and would be effective against yeast. I would not recommend using any topical medication unless it has been recommended by your veterinarian. Clobetasone is a corticosteroid and would not be recommended for some dogs.

For ringworm you need either Conofite lotion (Miconazole), or a similar anti fungal cream +/- an oral antifungal (i.e. Fluconazole or Ketoconazole). Ringworm can take 2-4 weeks to cure in most cases. Also shaving the hair around the lesions helps prevent further spread. It is also advised to was all of Bruno's bedding in really hot water to eliminate any fungal spores the environment that could re-infect him.

Only your vet can make the decision if it is acceptable or not to use Fluconazole with cetrizine with Bruno. Cetrizine is an antihistamine which is primarily used in humans, so it would be considered off label use in dogs. Because of this, only a vet who has a client patient relationship can safe if it is okay to use in a particular animal, and that is impossible to achieve this relationship via an internet forum. I recommend taking Bruno into the vet to discuss the use of these drugs together.

No, I would not use these on Bruno. First off, it's not safe to self treat your animal, as you may accidentally do more harm than good. Secondly, the common meds used to treat yeast infections in dogs include miconazole, itraconazole, and ketoconazole, which can only be prescribed by your vet. Finally, there are other causes for itching and redding skin in paws, such as allergies, and the underlying cause of this behavior needs to be diagnosed in order to be treated correct. If you are concerned that Bruno has a yeast infection, I would take him into the vet for an exam to confirm that he does have one, and the vet can prescribe an appropriate treatment for him.

Place an e-collar (cone) on Puppers to prevent further licking. This may be enough to allow healing but if not, wash the affected paw with a mild antibacterial soap or a diluted chlorhexidine solution. Dry thoroughly and apply plain cornstarch between the toes to keep the area dry.

Usually a veterinarian would perform a cytology to distinguish between a bacterial and fungal skin infection - they would take a sample on a microscope slide and examine for organisms. It's also possible that Bini has a resistant bacterial infection, or she might have another underlying disease process like an autoimmune disorder contributing to her symptoms. In your picture her foot does not appear classic for a fungal infection. You may want to follow up with your vet to discuss further testing and treatment.

The first thing I would want to ensure is that this is in-fact a fungal infection. Since you have seen multiple doctors, I'll assume they diagnosed it through a fungal culture or a positive response to a UV light. If this has not been done, then I highly recommend you have it done. If it's definitely ringworm, then you will have to treat this for a long time before it goes away. It can take a few months sometimes. The terbinafine cream is helpful, but for an infection that has spread all over the body, I would be giving the dog antifungal tablets. You will need a veterinarian to prescribe these.
