Friend, as you already know it sounds like Lola is suffering from allergies (food or environmental). Besides treating her paws topically for any sores I would also recommend you consider doing a food trial for 6-8 weeks. This is what you can do:
1- Change her diet to a prescription food called Hill's z/d, this food is only available through your veterinarian. Or, you can try a grain free diet with a different source of protein then what she normally has had in the past. For example: If she seldom ate fish then put her on a food that has fish. You can buy a grain free diet over the counter in any pet store. When on the new diet she should not eat anything else or she will not improve, no table food. Needs to be on this diet for 6-8 weeks before you see significant improvement. For treats you can give veggies like broccoli, cauliflower, baby carrots, etc.
2- If she is not doing well on Benadryl you can try a different anti histamine like Chlorpheniramine 2mg every 8-12 hours.
3- Supplement with Eicosaderm (omega 3 fatty acids); you can buy this over the counter in any pet store or online. Give at label dose.
For the sores on her paws this is what you can do:
1- Need to stop her from licking or she is going to delay healing. Pick up an ecollar (cone) in your local pet store to stop her from licking/gnawing at affected area.
2- Pick up in your local pharmacy "Hibiclens" antimicrobial soap or chlorhexiderm scrub. Wash area with this soap 2-3 times a day. If you do not find the above soap use over the counter antibacterial soap.
3- After washing affected area as above apply a topical antibiotic like neosporin or bacitracin. Do this 2-3 times a day for the next 7-10 days.
4- If no significant improvement after doing the above discuss with your vet about using a medication called Apoquel for allergies.
