Travel and Diet

Traveling can be stressful for dogs. Proper planning helps prevent diarrhea, loss of appetite, and other issues.

Golden Rule: Stick to Their Usual Food!

NEVER switch food before or during travel — stress + new food = digestive problems.

  • Bring their regular food (pre-portion it)
  • Don't rely on local availability
  • International travel: check availability beforehand

1 Week Before Travel

Health:

  • Probiotic course
  • Deworming up-to-date
  • Vaccinations current
  • Passport/microchip

Mental Preparation:

  • Short practice trips
  • Familiarize them with the carrier/crate
  • Ensure it's not a place of punishment

Car Travel

Morning of Travel:

  • DO NOT feed immediately before departure (can cause vomiting)
  • Small meal 2 hours before departure OR just water before leaving

During the Trip:

  • Stop every 2-3 hours for a break (water + potty)
  • Fresh water in a bottle
  • Limit treats in the car

Upon Arrival:

  • Wait for them to calm down
  • Offer half a portion of light food
  • Plenty of water

Air Travel

  • Vet's approval/health certificate
  • Last meal 4-6 hours before flight
  • Plenty of water before check-in
  • Crate: attachable water dispenser

Brachycephalic breeds (Pugs, French Bulldogs) are often NOT allowed to fly with many airlines due to heatstroke risk.

At Your Destination: The First 24 Hours

New environments cause stress. Dogs may experience:

  • Reduced eating (20-40%) for 1-2 days
  • Possible diarrhea or vomiting
  • Open to new situations, but tired

What to do: stick to usual feeding times, use their familiar bowl, provide a quiet space, no new treats.

Water Intake During Travel

Stress + car + new climate = frequent dehydration.

  • Own portable bowl
  • Own water (gradual mixing if using local water)
  • Bone broth ice cubes as a snack
  • 50% wet food mixed with dry kibble

Boarding Kennel

  1. Bring their own food for 1 week (portioned into bags, labeled)
  2. Their own bowl, blanket (familiar scent)
  3. Written feeding instructions
  4. Health background (allergies, medications, vet contact)

Car Sickness (Kinetosis)

Symptoms: drooling, nausea, vomiting, restlessness.

What to do?

  • Empty stomach at departure (last meal 2 hours prior)
  • Plenty of fresh air (windows, AC)
  • Frequent breaks
  • Maropitant (Cerenia) — vet prescribed
  • Small amounts of ginger
  • Lavender oil in the crate

International Vacation

Heat: avoid midday walks, keep food cool. Beach: saltwater = vomiting, sand = stomach cramps, 1-hour rest after eating (to prevent GDV). Mountains: 2000m+ (approx. 6500ft+) appetite may decrease, more water, +10% calories (due to cold).

Returning Home

  • For the first 24 hours: normal food, half portion
  • Plenty of water, rest
  • Diarrhea: rice + boiled chicken for 2-3 days

5 Common Mistakes

  1. "Homemade food is fine here" — sudden diet change
  2. "Extra treats for stress" — upset stomach
  3. "Buying new food from a local store" — never
  4. "Withholding water to prevent vomiting" — dehydration
  5. "Skipping probiotics" — diarrhea upon return

Warning Signs

🚨 See a vet after travel if: diarrhea for 2+ days, vomiting for more than 1 day, loss of appetite for 3+ days, lethargy, blood in stool/vomit.

Packing List

Food & Feeding: 1+ week of usual food, own bowl, water bottle, familiar treats, bone broth ice cubes. Health & Safety: medications, probiotics, anti-emetic, first-aid kit, vet contact info. Comfort & Essentials: blanket, pillow, toys, passport/microchip info, leash.

Special Diets While Traveling

  • Diabetic: fixed feeding times + insulin
  • Allergic: ONLY their own food + treats
  • Kidney/Liver disease: MUST bring their specialized food
