If he's in the mood to play, wait until he's lounging before approaching him for paw-handling training. Start by touching your dog's paws gently. If he doesn’t pull away or resist, start massaging the paw and gently pressing on his nails. Depending on your dog’s age and temperament, it may take a few sessions before he's used to paw handling. Repeat this exercise a few times daily until your dog stops reacting to paw handling. If your dog's had a bad experience in the past, he may resist nail trims.

Trauma usually only occurs in one nail and is caused by running on rough surfaces, catching a nail on an object, or improper nail trimming. Trauma or health conditions like diabetes and low thyroid levels can lead to bacterial infection in the nail. Bacterial infections usually cause swelling, pain, and discharge around the nails. Fungal and parasitic infections are less common than bacterial infections but cause similar symptoms. Tumors can take different forms: lumps, bumps, swellings, redness, or discharge. Immune...
