If your pet is prone to sickness, arrange to see your vet well before your holiday. There are several products which can help to reduce the effect of travel sickness but they have to be given before you start your journey.
There are some very basic common sense guidelines for travelling with pets. Firstly animals need easy access to fresh water at all times. They can go without food for a few hours but water is essential. Fresh air and temperature control is just as important.
Dogs will need the chance to stretch their legs and relieve themselves every couple of hours so journey times will be longer than you might expect.
In general, it is not a good idea to travel long distances with cats. They are far safer at a good cattery or at home with a trusted and capable visiting carer. Cats should never be transported loose in the vehicle. Use a good cat carrier and ensure that the carrier has a comfortable blanket with absorbent newspaper beneath.
Perhaps consider taking your pets to the cattery or kennels a day ahead of your departure. You should check the opening hours of your kennels or cattery and make sure you arrive there well within the published times. Take all the vaccination cards, special foods or medicines, a written summary of your contact details and local emergency contact.
