Making up

Stitch two buttons onto the collar so that the collar can fasten.

If you do not wish to use buttons or knit the buttonholes, press studs are an alternative.

Press the coat lightly on the wrong side with a warm iron over a damp cloth avoiding the garter stitch borders.

Sew the belt to the center back of the coat and fasten it with two buttons or press studs.

An Easy-Level Knitting Pattern

This is an easy pattern for those of you who are advanced beginner level, and the techniques you will need to know are knit, purl, and work with two colored yarns simultaneously.

Using mainly knit and purl stitches it simply decreases the shaping.

The dog coat has a different colored edging, which requires a little intarsia technique to do.

The Dog Christmas Sweater Sizes

This dog coat is available to knit in three sizes: small, medium, and large.

Measurements in inches about;

  • Width: (16, 21, 26)
  • Length excluding collar: (13, 17, 21).

My dog Jason is wearing the large size in the photographs, as the medium was too small for him, and the large is just slightly big on his frame. 

He is a medium/large-sized dog and weighs in at 23 kilos, so the large size was the right choice.

The Yarn I Used

  • The dog Santa outfit has been knit on 9 mm (US 13) needles with super bulky yarn 06.
  • The recommended yarn for this pattern is Lion Brand Wool-Ease Thick and Quick, or Hometown USA.
  • Any super bulky yarn that can be used with the recommended needle size is acceptable.
  • Not a whole skein is needed for the belt or the belt buckle.
  • The main body of the coat is knit with two colors, white and red.
  • The white yarn is knit in garter stitch and forms a border around the coat.

The Collar and Belt Fastenings

  • The dog sweater is then fastened at the collar with two buttons.
  • But if you do not want to use buttons, press studs are a good alternative. 
  • This is the same for the belt fastening.
  • I used two black buttons, but press studs can be used again.
  • If there is a chance your dog might try to chew off the buttons (*ahem* Jason!), press studs may be a safer option!
  • The belt accessory is knit in one long piece, using garter stitch only.
  • The belt buckle is knit in five pieces, four sides of the rectangle, and then a middle length.
  • There are photographs in the pattern instructions below that will help you to create and assemble the belt buckle.

Is It OK For Dogs To Wear Costumes?

It can be okay for dogs to wear costumes, but it’s important to consider a few factors to ensure their comfort and safety:


  • Ensure the costume is comfortable and doesn’t restrict breathing movement or cause discomfort. Look for soft, breathable fabrics that won’t irritate their skin.

Proper Fit:

  • Choose a costume that fits well without being too tight or too loose. Avoid any parts that could become a choking hazard or restrict their vision or hearing.


  • Always supervise your dog while they’re wearing a costume. Some dogs may try to chew or remove the costume, which can pose a risk of choking or ingestion.


  • Pay attention to your dog’s behavior while wearing the costume. If they seem stressed, anxious, or uncomfortable, it might be best to forgo the costume.


  • Consider the weather conditions. Costumes with excessive layers or that are too warm can cause overheating, especially in warmer climates.


  • Introduce the costume gradually. Let your dog sniff and explore the costume before putting it on. Use positive reinforcement and treats to create a positive association.


  • Avoid costumes with small, dangling, or easily chewed-off parts that could be a choking hazard or cause injury.


  • Limit the duration your dog wears the costume. Some dogs might be fine for short periods, like during a photo session, but might not be comfortable wearing them for extended periods.

Check for Signs of Discomfort:

  • Watch for signs of distress such as panting excessively, trying to remove the costume, or behaving unusually.

Ultimately, every dog is different, and while some might enjoy dressing up, others may not feel comfortable.

Always prioritize your dog’s well-being and comfort when considering whether or not to dress them in a costume.

If your dog seems happy and relaxed in the costume, and you’ve taken the necessary precautions, then it can be a fun way to include them in festive occasions like Christmas morning.
