GETTING YOUR DOG COMFORTABLE WITH NAIL TRIMS
Most dogs are uncomfortable with their human "holding hands" with them, which is also the reason they object to having their paws held during nail trims.
Dogs' paw pads are loaded with nerve receptors that help protect them when they walk and run. These receptors also make their paws more sensitive to handling than other parts of their body.
The last thing you want to do is hold your pet down or with an overly firm grip, this can increase the fear level, which can lead to a fight-or-flight response.
Incorporate paw touches into petting. Do this by stroking the head and body then working your way to the paws.
If the only time you touch your dog's feet is to trim her nails, she will immediately know what's coming when you touch her paws.
Another thing to keep in mind is not to rush, you can always go back and take a bit more off but you can't erase the pain memory if you cut one too close.
If you create a painful experience for your dog during nail trims, she'll forever associate trimming with pain.
I recommend the use of food treats, soothing speech and cuddles to create positivity around nail trims.
Also, to start off, only trim one nail a day. Especially if your dog has a very low stress tolerance threshold.
Instead of trying to "get it over with", by doing one nail each day trimming can become a quick and relatively pleasant daily experience for you both and neither of you will become "stressed out!".
