When I am back home I stay with him for some days He has been with Royal Canin hipoallergenic for 6m, due to some interdigital furunculosis and generalised erythemaen-USTelligent Community 10https://www.vetsurgeon.org/thread/245571?ContentTypeID=1Sun, 29 Sep 2024 10:54:24 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:18f4510d-f9a9-41ab-8142-9dfe9765e0d4Tomas B<p>Hello Richard.</p> <p>Thank you for the reply</p> <p>Would the doxycycline or TMS affect the culture or histo? Can staph interm be resistent to amoxyclav?</p> <p>Considering the stagnated and disseminated (since multiple lesions, toe, ankle, interdigital) and ear infections etc, wouldnt a pyo from a food/environmental allergy dermatitis be the most likely differential instead of neoplastic?</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/245570?ContentTypeID=1Sun, 29 Sep 2024 07:19:52 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:fa9c5212-c834-4381-a6e9-04dad0831c6bRichard Carter<p>Think I would biopsy for histo and culture to start. Deep pyoderma can be really horrible. On the basis staph intermedius always resistant to penicillin, I would probably start trimethaprim or doxycycline for antibiotic cover, check for other causes of immunosuppression (hypothyroidism , HAC, neoplasia) hibiscrub soaking, your favourite skin tonic, bravecto or similar to remove possible demodex.</p> <p>You can do skin punch biopsy under local if ga an issue. Think a skin scrape will rule in/ out demodex, confirm infection vs tumour, possibly even point type of bacteria involved. Good luck&nbsp;</p><div style="clear:both;"></div>
