When do their heads stop growing? Baskerville Ultra Muzzle sizing.

I'm only asking because I'm trying to order a Baskerville Ultra Muzzle and based on Marquez measurements he needs to wear a size 3 (confirmed by a rep for the company in an email). His nose length is 3" and nose circumference 11"which does make him a size 3 but if his head is still going to grow, do I go for a 4 instead considering he is already at the max of the 3?

Looking at the age you said he is below your avatar he has at least two years of growing yet, first up and then out.
You may even need to go larger at a later date but for the next 6 months possibly a year i would go for a size 4, personally.

He's 14 months and have noticed that his body is definitely changing and have no doubt his head will too. I think I will get the 4 now - if it doesn't fit him just yet, no biggie as I just want it to train him to be used to it and have him comfortable in case we do need to use it one day so I can wait for him to grow into it if I have to. I'll just get a larger size when he grows out of it

Size 4 would be far too big IMO. My last foster was a lab/staff with a massive head and he was only a 3. All staffies that I've muzzled I kennels have been a 3 too. Biscuits quite dainty and a 3 hangs off her so she has to have a 2!!

Lola has a 3 but she has an average Staffy head, Lily would need a 4 as she has a bigger head   

I'd get a 3 Too Diane like rach suggests Xx

Thanks girls, looks like I'll be getting a 3 for him instead of going too big

Just thinking Lily borrows Lola's muzzle when my son takes her to play football. She is very socialised but will ruin a football in 2 mins so he puts the muzzle on to stop her biting the ball
