FAQ

What do terms like 'Small', 'Medium' and 'Large' actually mean for dog beds?

Generally, ‘Small’ is suitable for smaller breeds like Dachshunds or small terriers, measuring around 60-80cm in length. ‘Medium’ sizes typically fit breeds such as Cocker Spaniels or Border Collies, usually between 80-100cm. 'Large' beds are best for bigger dogs like Labradors or Golden Retrievers, generally 100cm+.

How is the height of a dog crate measured?

Crate heights are described as ‘Short’, ‘Medium’ and ‘Tall’. A ‘Short’ crate will only accommodate a dog with a limited back arch, around 35-45cm tall. 'Medium' crates suit most dogs with a standard back arch (45-60cm), and ‘Tall’ crates offer extra legroom for larger breeds exceeding 60cm.

What does 'XL' mean when buying dog coats?

'XL' stands for Extra Large and is designed to fit significantly bigger dogs, usually over 60cm in length and with a substantial chest measurement. You’ll need to check the specific measurements – chest and length – as sizing varies between brands.

I have a very small dog – what size bed should I consider?

For truly tiny breeds like Chihuahuas or Maltese, a ‘Small’ (60-80cm) bed is usually the most comfortable. Ensure it has raised sides to provide them with a sense of security and warmth.

How do I measure my dog for a harness?

Measure your dog's girth – around their chest, just behind their front legs – using a flexible tape measure. Add approximately 10-15cm to this measurement for a comfortable fit, referencing the manufacturer’s sizing guide.

What is meant by ‘Junior’ sized food bowls?

'Junior' bowls are designed specifically for smaller puppies and young dogs, often with lower rims to prevent them from spilling while eating. They typically measure around 15-20cm in height.

Can I buy a 'Large Breed' dog lead and it still fit my medium sized dog?

While ‘Large Breed’ leads can sometimes accommodate medium dogs, you must always check the specific measurements – particularly the handle length and loop size. A longer lead might be uncomfortable if they cannot manage it effectively.

What is a good method for measuring my dog's height for a stair gate?

Measure your dog from their paws to the top of their head using a tape measure, ensuring they are standing tall and relaxed. Add an extra 5-10cm for comfortable passage through the gate.

How do I choose the right size feeding mat?

Feeding mats are typically sized by length and width. A ‘Small’ mat might be suitable for a single small dog, while ‘Medium’ or ‘Large’ options will accommodate multiple pets or larger breeds.

What should I consider when choosing a dog bowl size?

Bowl sizes vary depending on your dog's breed and eating habits. Generally, a minimum of 30cm in diameter is recommended for most adult dogs to prevent them from leaning too far forward and straining their necks.

In depth

Measuring for dog beds is far more complicated than you might initially think. The industry doesn't adhere to standard sizes like you’d find for human furniture, relying instead on a system of measurements – length, width, and depth – that can be confusing for new pet owners. A bed labelled ‘Large’ in one retailer might feel considerably smaller than one described as ‘Large’ elsewhere. This is primarily due to variations in how manufacturers define these terms, often focusing on the ideal size for a medium-to-large breed dog rather than a universally agreed-upon standard. Furthermore, many beds are designed with a slight “nesting” effect – meaning they're slightly smaller internally than their exterior dimensions – to provide a comfortable and contained sleeping space for your dog.

The most common sizing system used is based on the size of the dog it’s intended for. ‘Small’ typically refers to dogs under 15kg, often small breeds like Chihuahuas or Maltese. A ‘Small’ bed will generally measure around 60cm x 75cm x 30cm – a snug fit that provides adequate space without feeling overly large. However, even within this category, there's considerable variation. Some manufacturers might consider a Jack Russell Terrier “small,” while others would classify a Dachshund as such. Therefore, it’s crucial to carefully review the product description and pay attention to the specific breed recommendations. ‘Medium’ beds generally cater to dogs weighing between 15kg and 30kg, with dimensions around 76cm x 91cm x 38cm. This provides a more generous sleeping area for breeds like Cocker Spaniels or Border Collies. Larger breeds, naturally, necessitate larger beds. ‘Large’ beds typically accommodate dogs over 30kg, measuring approximately 81cm x 102cm x 46cm. These are suitable for breeds such as Labrador Retrievers or German Shepherds and offer ample space to stretch out. Finally, ‘Extra Large’ beds – often exceeding 100cm in any dimension – are designed for exceptionally large dogs like Newfoundlands or Mastiffs.

A significant source of confusion arises from the differing depths of dog beds. While length and width are relatively straightforward, depth (the distance from the top of the bed to the base) is frequently overlooked. A shallow bed might be comfortable for a short-legged breed like a Pug, but it won’t provide sufficient support for a taller breed like a Collie. Conversely, a deeply cushioned bed can feel overwhelming for a smaller dog and may lead them to push their paws underneath, rendering the bed unusable. Always consider your dog's sleeping style when choosing the depth – do they sprawl out, curl up, or prefer a more contained space?

When assessing whether a bed will fit in your home, it’s essential to measure the available space accurately. Don’t just rely on room dimensions; factor in furniture and walkways. A bed that looks perfectly sized in the retailer's showroom might not fit comfortably against a wall if there isn’t enough clearance. Furthermore, consider doorways and hallways – will the bed be able to navigate these spaces easily? It's always wise to add an extra 10-15cm to both length and width measurements to account for rounding errors and allow for comfortable positioning.

The most common sizing mistake is focusing solely on the dog’s weight without considering their breed and body shape. A 20kg Labrador, for example, will require a significantly larger bed than a 20kg Greyhound due to differences in build and sleeping habits. Breed-specific recommendations are invaluable guides – researching the typical sleep needs of your particular dog breed can help you select the most appropriate size bed. Don’t assume that all ‘Large’ beds are suitable for large dogs; meticulously check the dimensions and consider your dog’s individual requirements.

Finally, remember that many manufacturers add a small amount of padding to their beds, so if your dog is a particularly restless sleeper or likes to shift around frequently, you might want to opt for a slightly larger bed than initially suggested to ensure they have enough room to move comfortably. It's better to err on the side of generosity when it comes to providing a comfortable and secure sleeping space for your canine companion.
