Cascais relies mainly on the CP Linha de Cascais commuter train (40 minutes to Lisbon Cais do Sodré, twice an hour), the Carris Metropolitana bus network and Bolt/Uber rides — and all three are friendly to dogs and cats under reasonable conditions. The CP rule of thumb: small pets in a carrier travel free, larger dogs need a short leash plus muzzle and a current vaccination booklet.
| Mode | Policy | Tip |
|---|---|---|
| Small pets free in a carrier (hand-luggage size); larger dogs on a short leash with muzzle, vaccination booklet and municipal licence | 💡 | |
| Pets in a closed carrier travel for free; loose dogs only at the driver's discretion, generally outside rush hour | 💡 | |
| Both apps offer a "Pet" filter in Greater Lisbon; standard rides may accept dogs at the driver's discretion, expect a €1–2 cleaning surcharge | 💡 |
