Learn steps you can take to help your dog feel comfortable in their e-collar. Our veterinarian informed us t hat Mary Berry wear her e-collar for 14 days after her spay so the area was completely healed before she had access to the area again. When cones are removed too quickly, and the dog is allowed to lick, scratch, or chew their incision site, wound, or hot spot, it could result in delayed healing, prolonged treatment, or other problems.
