Here's why:
- The shampoo used during the bath can leave a residue on the puppy's fur, which can interfere with the flea collar's effectiveness.
-When a pet's fur is wet, it can absorb more of the chemicals from a flea collar, which could lead to an overdose for your puppy.
-The chemicals in the flea collar can also irritate your puppy's skin, especially if they're already wet and sensitive.
It's best to wait at least 24 hours after giving your puppy a bath before putting on a flea collar. This will give the puppy's fur enough time to dry and for the shampoo residue to wear off, thus ensuring the flea collar's effectiveness and preventing any potential skin irritation.
