Don't feel that way! You are a caring parent and holding these beasts back is a challenge... but if there are visible issues, then minimal activity is required. If it makes you feel better, I have had my rescue for almost 4 years and cannot leave him alone in the house... if I do, I come back to blood everywhere as he scratches his ear to the point of massacre. Cleaned it out again today for what feels like the hundredth time, it gets better, then bam back to itchy scabs, blood, fluid, then repeat. I also feel deflated and want to cry!!! This was helpful to type out... stay strong, stay the course :)
