Buying advice

When choosing a flea collar, consider your dog's weight and age, the duration of protection needed (most last 7-8 months), and whether your dog swims often (waterproof options like Seresto are best). For sensitive skin, look for collars with natural ingredients or consult your vet. Always ensure the collar fits snugly but not too tight, and trim any excess length.
