You should never give your pet a pain reliever without first contacting a veterinarian. Tylenol is toxic to cats and the effects of this drug have not been thoroughly researched for dogs. Aspirin should be given only after consultation. If your pet doesn't take heartworm pills, he should begin to before you leave. More and more widespread, heartworm disease is a greater risk in some geographical areas than others.
Animals are creatures of habit who prefer to keep to the same routine.
Once settled, try to maintain the same schedule and routines for feeding and exercising as you would at home. It is wise to confine your pet to a hotel room, garage or other limited space for several days before allowing him more freedom, Your pet will need to recognize his new home, whether it is permanent or temporary, before he can be trusted to return to it. The kennel in which your pet is traveling must be an airline approved model. One can be purchased from a pet store. If your kennel is a few years old, contact the airline and ask if it still meets airline safety standards.
