Why are beaches sandy or pebbly? It’s simple, really. It just depends on the kinds of beaches they are. Cliff areas tend to have higher stronger waves, so have more pebbles. And sandy beaches tend to be areas with gentle waves. The colour depends on the content (for instance, iron oxide makes sand brown, but abroad coral quartz makes Caribbean sand white or pink – you can even find green sand).

Check tide times and avoid sinking mud. Never take pebbles from beaches (illegal in Italy) as it disturbs ecosystems. Keep dogs away from seaweed (they like to play with fronds) as it expands in the stomach as it dries. If exploring rock pools, leave creatures alone (crabs etc) as many are injured, once returned to sea. Wear natural rubber wellies (not flops) as wet rocks and seaweed are slippery. 

Dogs are curious, but even dead jellyfish can sting, and lion’s mane jellyfish and Portuguese man o’war in particular can be dangerous. If your dog is stung, rinse area with sea water, remove tentacles/barbs and seek immediate vet advice.
