What is a IATA Certified Pet Crate?


If you are planning a flight with your pet, the term “IATA-compliant” will quickly come up. IATA (International Air Transport Association) sets global guidelines for how animals should be transported by air.


An IATA-certified pet crate is not a specific brand, but a crate that meets strict construction requirements defined in the Live Animals Regulations (LAR).


These rules exist for one reason: to ensure your pet remains safe, secure, and comfortable during the flight. Most airlines will refuse your pet at check-in if the crate does not meet these standards.



Essential Crate Features for Airline Approval


Not all plastic crates are equal. Even if a product says “airline approved,” you must verify the physical features yourself.


A proper airline crate must have:


  • Rigid shell material
    Made of strong plastic. No collapsible or foldable crates.
  • Metal door and fasteners
    The door must be metal with a secure lock. The top and bottom must be connected with
    metal bolts, not just clips.
  • Ventilation on multiple sides
    At least 3 sides (4 is better for international flights).
  • Water and food bowls
    Must be attachable to the inside of the door and accessible from the outside.
  • No wheels attached
    If the crate has wheels, they must be removed before check-in.



How do I measure my dog for a flight crate?


(Let's focus the example on dogs for now since their larger size can be a bigger issue than cats).


Getting the size right is the most common issue for first-time travelers. If the crate is too small, your dog may be rejected at check-in. If it’s too large, your dog may not be stable during transport.


To measure correctly:


  1. Length (A): Nose to base of tail
  2. Width (B): Widest part of the shoulders
  3. Height (C): Floor to top of head or ears



What airlines expect:


  • Crate length = A + extra space
  • Crate height = C + clearance above ears
  • Dog must be able to stand, turn, and lie down comfortably



Real-world example:


If your dog is:

  • 60 cm long
  • 45 cm tall


👉 You should look for a crate around:

  • 70–75 cm length minimum
  • 50–55 cm height minimum


If your dog is close to the limit → always size up.



Crates that get rejected at the airport


This is where many travelers go wrong. Avoid these completely:


  • Metal bar crates (home/training crates)
  • Collapsible or foldable crates
  • Soft carriers (for cargo travel)
  • Crates that are too small
  • Crates with wheels still attached


Even if they look strong, they will not be accepted for flights.



Final checklist before flying


Before heading to the airport, confirm:

  • Crate is rigid plastic with metal door
  • All parts are secured with bolts
  • Wheels are removed
  • Your dog fits comfortably
  • Water bowl is attached
  • Bedding is absorbent
  • Airline rules are confirmed


Choosing the right dog travel crate is not about finding the most expensive option - it’s about choosing the right type and the right size.


If you follow the guidelines above and select one of the recommended crates, you significantly reduce the risk of:


  • Check-in rejection
  • Travel stress
  • Safety issues during the flight


And that’s what makes the difference between a smooth journey and a costly mistake.

A structured grooming routine significantly improves the travel experience for pets and their owners. When pets feel clean, comfortable, and physically well, holidays become smoother, calmer, and safer. At PETsTourism.com , we encourage responsible pet travel. Below is a professional yet practical hygiene and grooming checklist you can use during your stay in Portugal. Checklist: Hygiene and Grooming While Traveling Presented by PETsTourism.com Daily Care Routine Small daily actions prevent bigger problems. Dental Care Brush your pet’s teeth using animal-specific toothpaste. This prevents tartar buildup and bad breath during travel. Changes in water or diet while abroad can sometimes increase plaque formation. Paw Inspection Especially important in Portugal. Check paw pads for: Sand Grass awns (locally called espiguilhas) Small stones Irritation from hot pavement Portugal’s surfaces can be rough and extremely warm in summer. Coat Maintenance A quick daily brushing removes loose hair, dust, sand, and debris after outdoor activities. Weekly Care Routine Consistency prevents infections and discomfort. Ear Check Inspect ears for redness, odor, or discharge. After swimming in the sea or a pool, ears must be thoroughly dried to prevent infections. Thorough Brushing A deeper grooming session prevents matting, especially in long-haired breeds. Coastal humidity combined with sand can quickly create tangles. Monthly Care or As Needed Nail Length Check if nails touch the ground while your pet is standing still. If they do, trimming is necessary. Long nails can cause joint strain during longer holiday walks. Bathing Wash your pet with a mild dog shampoo. Tip: Bathe your dog at the end of your holiday to remove accumulated sea salt, sand, and dust before car or air travel. Portugal-Specific Grooming Advice Portugal’s climate and environment require extra attention. Heat Management For long-haired dogs, properly brushing out the undercoat improves airflow and helps regulate body temperature in warm weather. Parasite Prevention Portugal has sandflies and ticks. During grooming sessions, always check for: Ticks Skin irritations Bite marks Preventive treatment against Leishmaniasis and tick-borne diseases is strongly recommended. Hydration Fresh water is part of hygiene. Proper hydration helps prevent urinary tract problems and supports overall health, particularly in hot climates like Portugal's summers. Why This Matters Professional-level grooming is not about luxury. It is about prevention. Daily checks catch problems early. Weekly routines maintain comfort. Monthly care supports long-term health. When pets feel good, travel feels good. For more practical travel guidance and pet-friendly accommodation across Portugal, explore PETsTourism.com .

Portugal has beautiful gardens, lush villa landscapes, and colorful roadside plants. But here is the reality - many popular plants that thrive in the Algarve and across Portugal are toxic to dogs and cats . For guests of PETsTourism.com , this is essential knowledge. Tourists often assume the flora is similar to Northern Europe. It is not. If you are staying in Portugal with pets, especially in private villas, holiday homes, or rural areas, read this carefully. Common Toxic Plants in Portuguese Gardens Below are the most frequent toxic plants found in the Algarve and throughout Portugal.

If you are staying in Portugal between January and May , this is not optional knowledge. The Pine Processionary Caterpillar can be extremely dangerous for dogs . Every year, pets suffer severe injuries because owners simply did not know what to look for. This guide from PETsTourism.com explains exactly how to recognize the risk, what to do in an emergency, and how to prevent contact. What Is the Pine Processionary Caterpillar? The Pine Processionary Caterpillar (Thaumetopoea pityocampa), known in Portuguese as Lagarta do Pinheiro, is common in Portugal, especially in areas with pine trees. The danger comes from their microscopic toxic hairs . These hairs: Cause severe allergic reactions Trigger intense inflammation Can lead to tissue necrosis (especially of the tongue) May cause breathing obstruction in severe cases For dogs that sniff, lick, or step on them, exposure can escalate within minutes. When Is the Risk Highest? The danger period is January to May , with peak risk in early spring. In late winter and early spring, the caterpillars leave their nests and move in long nose-to-tail lines across the ground to pupate. This is when dogs most often encounter them. And here is the hard truth - pine forests are everywhere in Portugal (and Spain), not just in remote countryside areas. How to Recognize Them 1. The Nests Look up. You will see white, cotton-like nests high in pine tree branches. These are highly visible and often look like white balls stuck to the tree. 2. The Caterpillars In spring, they move in long processions across the ground, forming what looks like a small moving train. If you see a line of caterpillars - do not approach. Turn around immediately. Symptoms After Contact If your dog has touched or licked one, you may notice: Excessive drooling Swollen tongue or lips Pawing at the mouth Vomiting Signs of pain or distress Breathing difficulty This is a medical emergency. What To Do If Your Dog Has Contact Do not hesitate. Every minute matters. 1. Rinse Immediately Flush your dog’s mouth or skin with large amounts of lukewarm water. Important: Do NOT rub the area. Rubbing breaks the hairs and releases more toxin. 2. Go to a Veterinary Emergency Hospital Drive immediately to the nearest 24-hour veterinary hospital. Permanent damage can occur very quickly. 3. Protect Yourself Wear gloves if possible. The hairs are also irritating to human skin and eyes. Prevention Tips for Dog Owners in Portugal You avoid 95 percent of incidents by being disciplined. Keep your dog on a leash in forested areas between January and May Avoid walking directly under pine trees on sunny early spring days If you see a procession, make a wide detour Warn other dog owners nearby This is not an overreaction. It is basic risk management. Final Advice from PETsTourism.com Portugal is an incredible country for dogs, but nature here comes with different risks than Northern Europe. If you are staying between January and May, stay alert around pine trees. One careless moment can lead to surgery, permanent damage, or worse. Be proactive. Stay informed. And protect your dog the smart way.

Veterinary care in Portugal is generally good quality and affordable compared to many Northern European countries. Still, prices can vary significantly depending on region, clinic type, and treatment . If you’re travelling with your pet, relocating, or advising international clients, this guide gives you a realistic overview of common veterinary intervention costs in Portugal , plus a few local insights that can save money and stress. Regional Price Differences in Portugal One of the biggest factors influencing veterinary prices is location . Algarve & Lisbon region Prices are usually at the higher end of the range and may occasionally exceed it, especially in 24/7 hospitals and tourist-heavy areas. Interior regions (Alentejo, Beira Interior, near the Spanish border) Veterinary care is often significantly cheaper , with lower consultation fees and reduced labour costs. For travellers, this means emergency care near the coast may cost more - but access and English communication are usually better. Medication: Vet vs Pharmacy In Portugal, medication is commonly sold directly by the vet after consultation. This is convenient for acute treatments. However, for chronic medication (heart medication, long-term anti-inflammatories, etc.), it is often cheaper to: Ask the vet for a prescription Buy the medication at a regular Farmácia (pharmacy) This is a useful cost-saving tip for long stays or expats. Legal Requirements: Microchip Registration (SIAC) Since 2019, microchipping and registration in the national database is legally mandatory . Portugal uses the SIAC (Sistema de Informação de Animais de Companhia). Registration fee: usually around €2.50 In practice, this fee is often included in the standard microchipping price (€23–€30) Important for administration, travel, and proof of ownership Good to know when handling paperwork for international clients. Pet Insurance in Portugal (Growing, But Still Limited) Pet insurance is less common than in Northern Europe , but adoption is growing. Portuguese insurers increasingly offer pet packages, including: Fidelidade Médis These “Pet” or “Petis” plans may: Reduce consultation costs at partner clinics Offer limited coverage for diagnostics or treatments Coverage is improving, but it’s still important to check exclusions carefully , especially for pre-existing conditions. Quick Reference: Common Veterinary Prices in Portugal Basic consultation: €25 – €40 (excluding medication and tests) Annual vaccination (cocktail): €35 – €50 (dog DHPPI / L4) Leishmaniasis test: €25 – €40 (v ery important in Portugal) EU Pet Passport: €15 – €25 (often required for travelling pets) Prices are indicative and vary by region and clinic. Why Disease Awareness Matters in Portugal Portugal is a high-risk country for: Leishmaniasis Heartworm Many Northern European pet owners are not familiar with these diseases, yet prevention is essential - especially in warmer regions like the Algarve. For travellers using PetsTourism.com , this awareness is a major advantage and part of responsible pet travel. Final Tip: Budget for the Unexpected Veterinary care in Portugal is generally fair and transparent, but emergencies, night visits, multi-day stays and coastal regions can add up quickly.
