Yes, it is safe — PVC-coated webbing is hypoallergenic and latex-free, making it a great choice for dogs with sensitive skin. Because it's non-porous and doesn't absorb moisture, it's less likely to harbor the bacteria and mold that can cause skin irritation with fabric collars.
That said, any collar — regardless of material — can cause irritation if it's fitted too tight, left on when wet for extended periods, or not checked regularly. We recommend:
• Fitting the collar snugly but with room for two fingers between the collar and your dog's neck
• Checking under the collar regularly for any signs of redness or irritation
• Removing the collar during rest time if your dog is prone to skin issues
If your dog has a known allergy or skin condition, always check with your vet first.
