Muzzle FAQs: How to Measure a Muzzle

Awhile back, Muzzle Up! asked you to send in questions about muzzles, muzzle safety, muzzle training, and anything else muzzle-related. Unfortunately, there’s a shortage of quality information on this topic, let alone an easy way to find answers to questions. With your support, our ongoing “Muzzle FAQ” series will bridge this information gap.

Here’s a selection from the first batch of questions we received. Thank you to everyone who sends us notes and participates in our Facebook community. Together, we can erase muzzle stigma, one dog at a time.

Q: “I loved the Paul Frank muzzle taping idea so much I bought a couple of rolls online…but ack! The tape is all peeling off…did you treat the Baskerville with something first?”

A: This question refers to our muzzle art project from earlier this year, in which we wrapped decorative duct tape around a Baskerville muzzle. The concept is still a work in progress, but luckily several Muzzle Up! supporters are giving it a try! Our one tip is to try keeping all loose ends of the tape wrapped up to prevent fraying and water damage.

Q: Where can we find more fun muzzles? Black is so boring.

A: Depending on where you live, there are various stores that sell colored muzzles. For those in the US, Baskerville sells a powder blue colored muzzle on Amazon (they discontinued the pink color, unfortunately). See our muzzle equipment guide for other retailers.

Q: A good pictorial on how a muzzle should fit (particularly for bully breeds) would be great.

A: Muzzles should allow a dog to pant, drink water, and exercise comfortably (see our graphic attached to this post.)

Each muzzle brand has specific sizing specifications. We have created a graphic that shows the basic measurements you should take before purchasing a muzzle.

The following are links to sizing information for two of the more popular brands:

Q: How do you deal with the public when they see the muzzle and automatically think your dog is a biter? My dog has never bitten anyone but I know that people will see a so-called dangerous breed wearing a muzzle and jump to the conclusion that he is vicious. Also, does having your dog wear a muzzle effect your legal liability?

A: We created a blog awhile back that lists what many of our supporters say when facing questions about their dog in a muzzle.

Legal liability can vary depending on your region’s dangerous dog regulations. Check with your local police department for more information on dog bites and liability.

Q: Any tips for getting my dog to accept wearing a muzzle?

A: Training, training, training. Check out our website for videos  and instructionson training your dog to be comfortable wearing a muzzle.

  1. I am working with a dog that can paw the entire muzzle off. She is a lab/pittie X wearing a size 4 quick clip Baskerville ultra. I lengthened the strap between the eyes a little so it wasn’t angled upward so much and so it wasn’t so close to her eyes. They will get a collar to put through the muzzle to secure it better and continue working on longer duration. She willingly sticks her face in and will lick peanut butter or spray cheese while it is on. Any other suggestions?
    Thank you!

    1. Hi Connie! Great question. It sounds like you might be trying to ask her to keep the muzzle on for longer than she’s capable. Most dogs can get muzzles off if they really try – so it’s better to assume that if they’re trying to get it off, they need more practice/training. For example, work on leaving it on for 2-3 seconds, then 4-5, then 6-8, then 10, then 15, and so on. Gradually spacing out treats is hard, but important too!

  2. Any guidance for how to measure for a muzzle when there is a real risk of getting bitten while trying to do so?

      1. Hi Helen – Try getting “close enough” guess, and perhaps get a couple sizes that are close to each other, so if you put one on it looks too small you’ve got another one available. in a perfect world muzzles are perfectly sized, but in situations like this I would go for close enough.

  3. My dog is a doberman who eats everything! When we let her outside she has free run of 3 and 1/2 acres. We dont have fencing. She spends 98% of her time running and hunting. She eats who-knows-what and it makes her sick (she throws up, stops eating and sometimes stops drinking. This sickness lasts about 3 to 4 days). This happens about once a week. We, including the vet, think a muzzle is possibly the easiest and least invasive way to try and stop her from eating. We are having trouble finding a muzzle that accommodates her measurements. Her snout length is the problem. Do you know of a type that might work? It needs to allow her to pant freely and drink water. We appreciate any help you can give. Thank you. Chris and Will

  4. I’m trying to get started how and where to I buy a muzzle? I have a full grown catahoula.

  5. I am trying to fit my lab mix for his first muzzle. He will be 5 years old in April
    I am going to order a baskerville and a khonakollar. I contacted khona but have a question on sizing for the baskerville…. or is that even a good muzzle to start with? Indy is 66lbs. lean. snout measures 4 inches, mouth circumference is approx 12 inches. neck is 17 inches. seems like he is in between a size 4 and 5. Thank you- I think I will be looking on your sight for a lot of advice.

    1. Hi Melissa, thanks for your question. We like the Baskerville, but it can be tricky to get them sized right! Generally, we suggest purchasing both sizes from somewhere with a good return policy, and seeing which one works better.

  6. I have a pot bull, sweet, but, fear reactivity to nails being trimmed. I need a source to buy soft muzzles and muzzle patterns.
    I also have a Bernese Mountain dog that is a drug detection dog and cadaver dog. To protect my dogs from ingesting dangerous addictive drugs, and, deceased bodies can have bacteria that’s harmful to the cadaver dog, so, I need a source to buy a doggie N95 masks. Can you give me a good reliable supplier, pattern maker and manufacturer so I can add new pfotect my working dogs?

  7. Hi there- I am trying to figure out what type of muzzle to look at for my dog. He is a rescue mix (I think staffordshire terrier, beagle, and a lot of others mixed in!), but has shown territorial reactions (biting) to strangers at our home. What brand muzzle do you recommend to work with for this type of situation? Thanks so much.

  8. I have a 12 pound yorkshire terrier. He is terrible with children and snaps at them when they approach him. My husband is very much against a muzzle, but since we have 4 young great grandchildren I want everyone to be safe. I want my children to visit me, but due to the dog, they are very hesitant. I want to try a muzzle and see how he reacts to the children. I do not know what size or brand to buy. Can you help me

  9. I have a young dog, hand reared, mixed, who is becoming very aggressive; she attacks the older dogs in the house regularly. She is smallish with a long snout and long teeth. I am waiting for an appt with a behaviourist, but a muzzle was suggested. i will measure her tonight and submit for recommendations.

  10. We have a dog that has a wound on their leg and when the cone comes off (she needs a cone break or she uses it as a weapon) she goes after the area right away. Before we got her she has the same wound on her leg, had surgery on it and she then basically ate her leg. Would a Baskerville muzzle help and how long is it ok to keep it on her? She loves toys and rawhides.

  11. Hello ,

    I am trying to find the best muzzle for my dog. We need him to wear a muzzle to prevent him from ingesting random items outside. We want a muzzle that will be comfortable enough to wear for hours at a time (hiking, walks, park, etc.). We have looked into Baskerville’s but they seem like they would be too uncomfortable. Bumas is the best option we have found, however, they are expensive and take +1 months to get shipped to the US. Are there other comfortable muzzles out there?
