Here's why:
* Exposure to diseases: Puppies are more susceptible to diseases, and collars can increase the risk of exposure through contact with other dogs or contaminated surfaces.
* Risk of infection: If a collar is worn before vaccination, it can rub against the skin and create small wounds, making the puppy more vulnerable to infection.
Before 16 weeks, you can use:
* Harnesses: A harness is a good alternative, as it sits on the chest and doesn't put pressure on the neck.
* ID tags: Consider attaching an ID tag to your puppy's harness, even before vaccination, in case they get lost.
Once your puppy is vaccinated:
* Choose the right size: The collar should be snug but not too tight, allowing two fingers to fit comfortably beneath it.
* Consider a breakaway buckle: This can help prevent your puppy from getting caught on something and potentially choking.
* Introduce it gradually: Let your puppy wear the collar for short periods initially and gradually increase the time.
* Monitor for discomfort: Check the collar regularly for signs of irritation or rubbing.
Always remember to supervise your puppy when they are wearing a collar, especially when they are young and exploring their environment.
