The Question

“Dear Dr. Paola,

Teddy is around 10 years old. He was a drop off when I found him, I thought he was dying! He had sores that drained puss all over his body. I worked on him all the time and he is finally getting his hair back now, but he has a sore behind his ear that’s as big as half his head. I had been in the hospital for two months, and when I got home, he was missing. He was gone for six weeks; thankfully, I found him in my front yard. We need help. He is a fighter. He loves to go outside and sit in the sun and has a big heart. Can someone help us? We need you! Thank you,” – Teddy & Karen

Hi Karen,

Thank you for sharing Teddy’s journey. It’s incredibly moving, and it’s clear how much love and dedication you’ve poured into his care. The way you brought him back from such a fragile state speaks volumes about your compassion and determination. It’s heartbreaking to hear that after all he’s been through, he’s now dealing with another serious sore, especially one as large as you described behind his ear. Given the size and location, this could be a severe infection, an abscess, or something more complex like a growth or immune-mediated condition, particularly in an older dog with a history of skin issues.

Teddy’s strength and spirit are admirable. But at this stage, it’s important he’s seen by a veterinarian in person as soon as possible. He may need specific treatment like wound care, antibiotics, or diagnostics to understand what’s going on beneath the surface. I understand that with your hospitalization, this might be challenging at the moment. If money is the main concern, here are “15 Organizations That Help With Vet Bills” and “Crowdfunding for Vet Bills: 12 Tips How to Do It.” Hopefully, some of these ideas can help you to help Teddy. You’ve already done so much to give him a second chance; getting him proper medical attention now can help ensure he continues enjoying the sun basking and the life he clearly treasures.

Best wishes,

Dr. Paola
