My jack Russell mix has had her period for approximately a week. And yes they do swell up.
It doesn't matter what dog breed it is, on the average a dog will have a "heat cycle" twice a year, and it lasts for approximately 23 days.
12inches :) ;0 ;) go gators
they usually last for 1-2 weeks
Like most dogs a Jack Russell bitch will deliver her pups about 63 days after copulation.
Sometimes a jack russels nail is long and then breaks out if it is loose.no they can be clipped, they can fall off!theres lots of different reasons!
Usually above 13 years. I have a Jack Russell that is 14 years old and still going really well. They live longer that most dogs, for a small dog.
Mostly small dogs live that long jack russells yorkies chihuauas small poodles etc
yes it dose if you have been cry for a long period of time.
I have never known a Jack Russell which has died before 12 human years, (apart from the ones who have died of illness). My mother's old Jack Russell lived to 22 human years, so they live to very old.
No dog inherantly knows how to obey. It takes training and patience. I'd recommend finding a reputable trainer in your area with experience with JRTs that can help you train him.
It varies with the breed of terrier. Jack Russells have been known to make 20yrs.
No because a jack Russell terriers has hair. When hair sheds, it will float, unlike fur. Hair is on long haired dogs like pomerainians and jack russells. Fur is on short haired dogs like rat terriers and bull dogs. Fur will collect in the carpet and cause dander and allergy problems.
It will! I have done it before
