I adopted my boy in July 2020, aged 6. When I first got him he'd let me scale his teeth, clip his nails, brush his teeth. After about a month, he decided he didn't want his nails clipped, teeth scaled and barely tolerated the tooth brushing. I bought a Dremel and gradually acclimated him to that using peanut butter in a Kong to distract him. That worked well for several months, now he growls when licking the Kong if I try to Dremel his nails. So, in spite of always being gentle with him, he still doesn't trust that he isn't going to be hurt. So, my question is how to proceed. Just taking him to a groomer seems like a cop out - I feel like he needs to trust me enough to bandage his foot or pull out a thorn if needed. Anyone been down this road before?
