How do I take the measurement for my dog?

When taking the measurement for your dog, you make use of a soft tape measure against the surface of your dog’s skin to get the appropriate measurement in inches. Stretch it out from the beginning of the tape snug and form it around that part of the body you want to check just like the neck.

Any outfit for the neck you might want to make can be a pendant, a dog chain, a dog bead, or a piece of fashion item with a collar. You do the same for the trunk, back, or any other part of the body that you might need the measurement for in determining the right outfit.

Does the weight of my puppy affect the measurements?

How Big Will my Puppy Get?

People tend to have many questions after adopting a puppy; when my furry companion reaches adulthood, how large will they be? When do pups reach the point where they stop growing? What size will my mature dog grow to be? 

A quick google search often will not give these answers as quickly as you would like, especially for  cross-bred and multi-breed dogs

Weight and paw size measurements might help you estimate your puppy’s adult size. However, since small breeds such as the Shih Tzu, Charles Spaniel, Cocker Spaniel,  or Wheaten Terrier, medium breeds such as the Golden Retriever, large breeds such as the Mastiff and Bull dog mature at varied rates, these measurements may not be as accurate as you’d like.

Several factors can influence how big your small dog grows. While projecting a puppy’s mature weight and height isn’t an exact science, there are a few methods for estimating future growth and full size with accuracy.

Step 1: Determine your puppy’s weight.

This can be done using a baby scale or during a trip to a vet. But in cases where this is not possible, you can determine your pup’s weight using a standard bathroom scale.

  • Before you begin, double-check that the bathroom scale is set to zero.
  • Take your puppy and hold it carefully. It may wriggle around, but try not to drop it since it could get wounded. 
  • Climb the scale and wait a few seconds for it to calculate your weight. Check the number and make a note of it.
  • Reward your dog for not attempting to jump.
  • Climb the scale on your own
  • Get your weight and note it.
  • To determine the puppies’ weight, subtract your weight from what you received for yours and the puppy’s weight.

Step 2: Determine your puppy’s breed

You can do this by asking a vet for their opinion or ordering a DNA test. If you do not have immediate access to this, you can determine its approximate breed by assessing its physical characteristics such as:

  • Fur color
  • Fur length
  • Weight
  • Skull shape
  • Snout length
  • Tail characteristics

After getting these, use Petfinder or American Kennel Club breed evaluator to determine its approximate breed.

Step 3: Determine your puppy’s approximate age in months

Step 4: Use a dog adult weight calculator

Dog adult weight calculators such as Puppy Chart and Puppy Weight Calculator can help to predict your puppy’s adult size using the information collected above. They compare their present size to previous statistics from dogs of the same breed.

Importance of a dog size chart

A dog size chart helps you as a customer to have a mental picture and description of what you want to purchase. It also helps you purchase the right size of outfit without first making the mistake of returning it. You will really feel so confident in getting your dog outfits because you know the exact measurements that will fit.

A dog size chart, as a brand owner, reduces the room for much vague explanation to your customers. No matter how eloquent you are, you might have experienced explaining a particular thing to your customer and the more you try, it seems he isn’t getting it at all. A dog size chart, be it a bandana size chart or a chart that shows the muzzle size saves you the stress.

Once you get your exact measurement, check it on the dog size chart. You might even ask, “What if I get the measurement of my dog with a flexible measuring tape and don’t find the correct size in the sizing chart?” That might be possible when you are found checking the wrong muzzle sizing chart. Each brand model has its own sizing chart with different tags so it might be very complicated to compare one to another. You just need to make sure you get the exact measurements.
