How big is a fully grown Micro Pig or Teacup Pig?

In this guide we’ll take a look at Micro pig size – as it causes a lot of confusion. By the end of this article, you should have a clearer idea of just how big a Micro Pig actually is.

And I’ll also show you a few common scams and how to avoid some of the most frequent mistakes people make when buying a pet pig.

Micro pigs: How big do they actually grow?

The most common question asked about the Micro Pig is: how big do they grow? These days you can find more information online about this subject than ever before, however, you’ll still see a lot of conflicting opinions and advice.

Take this as a classic example: try using the Internet to search for images of Micro Pigs – click the link below to perform this search in Google:

You’ll find that the most common results returned are of the piglets and not usually of the adults.

Occasionally newspapers or magazines will write a story about these pigs and the same problem occurs. You’ll see pictures of the piglets and none of the adult pigs.

Why does this happen and what is the reason behind it? Simple: the piglets look cute and cute piglets make the articles more enjoyable. Typically you’ll see a cute little piggy in a teacup, or pictured with some celebrity, yet you’ll never usually see images of the fully grown adults (unless it’s some horror story of tiny pig turning into a 700lb giant farm hog). If the article does contain information about the adults, it’s often relegated to a few lines at the bottom of the page.

Micro Pig Size chart

Also any serious breeders should allow buyers to visit their farms/premises and see their pigs in person. When we were breeding pigs quite a few of the visitors to our farm were shocked by size of them.

But we believe that seeing a pet pig in person is the best way to dispel the myths surrounding the height. Also, it’s the best way to show people what’s involved when taking care of a pet pig.

At our farm we had plenty of visitors who left disappointed but happy. I think we prevented a lot of people from buying a pet they neither had the correct environment, nor the correct home in which to take sufficient care of one.

My point is this: any good breeder should allow you to come and see their pigs in person – in fact, a good breeder should encourage you to come and view them. They should also be knowledgeable about the breed and its requirements. If they aren’t, take your business elsewhere – don’t take the risk. If they’re clueless about the piglets they’re selling, they were probably clueless when they bought their parents.

Does size actually matter?

If you’ve been looking at classified adverts (either online or in magazines) for Micro Pigs, you’ll probably see the same claims being made by the sellers. They will usually be declaring that they have the smallest pigs in the business, and their pigs are inches smaller than the next seller’s. Usually they’ll have a few blurry photos, taken from the best angle possible, to back up their erroneous claims. Some breeders in the adverts might be telling the truth, other will be bending it, and others will be outright lying! Personally, I find this pitch flawed. Why? The reason is simple, and it’s something that we used to tell every customer who visited our farm:

‘The way you treat an animal makes a far bigger difference to its behaviour than whether the animal is large or small. The size of the pig (to a degree) does not make it easier or harder to keep. A pig which has been spoilt, or treated badly, will be a pain in the backside to keep regardless of whether it’s big or small. A couple of inches aren’t going make things any easier.’

Any pig which has been treated properly, kept outdoors correctly, and has not been spoilt, can be a real pleasure to keep.

Conclusion about Micro Pig Size

This chapter highlights the importance of finding a good breeder, one who knows the breed and provides you with good quality information and advice. It can be difficult to find a good Micro Pig breeder as there are no registered micro clubs monitoring the breed or its breeders.

A few key steps to take are:

  1. Ask the breeder plenty of questions – do they appear knowledgeable? Do the answers they provide tie in with the things you’ve read in this and other books?
  2. Ask for testimonials – some breeders might be able to provide written testimonials or put you in contact with previous customers.
  3. Look for a breeder who’s been established for a few years. If they have had a website online for a few years that’s a start. If they were a ‘fly-by-night’ breeder chances are they probably won’t have gone to the trouble of maintaining a website.
  4. Ask on Internet forums – in the useful links section at the end of this book there are links to websites where you can ask questions. Also there are many animal forums and Q&A sites you can ask your questions on. These could help.

The key to this process is – do your research before committing to anything and don’t rush in. The best way to stop yourself from being scammed is to arm yourself with knowledge. Most bad breeders, in my experience, don’t know a lot about pigs. Make sure you do.

Here are a few extra points worth considering:

  1. If you want the very smallest pigs possible buy black piglets. They have more Potbellied genes in them, this results in black pigs being smaller, on average, than their coloured counterparts. Usually they are cheaper as well. Good quality Potbellied Pigs can be very small – so they are worth considering.
  2. Coloured Micro Pigs are usually bigger than the black pigs. They have the DNA of other pig breeds in them. This results in their size, shape and frame being bigger than that of black piglets.
  3. As stated earlier, and from our own experience of breeding these pigs, the size and shape of the animal does not make them easier or harder to keep. The most important aspect of keeping a pet pig is how it is treated and making sure it is provided with the correct home environment.
  4. Pigs are fully grown when they are around three years old. When you are looking at piggy parents make sure you find out how old they are. If the piglets’ parents are under three years of age, they themselves will grow a little more – the piglets you are viewing will potentially grow to be bigger than their parents.
