My jack Russell mix has had her period for approximately a week. And yes they do swell up.
A Staffordshire Bull Terrier wins Best of Breed every year. Best of Breed is the Best dog from each breed, so there will always be one from the Staffy breed. This year (2011) a red Staffordshire Bull Terrier came third in Best in Group but a Staffy has never won Best in Show.
They remain active well into their 15-year-plus life span; their need for activity and desire to hunt continues for their entire lifetime. Untrained, unsupervised dogs rarely meet their life expectancy.Hope I helped !
According to the Jack Russell Terrier Club of America breed standard, a true Jack Russell is between 10 and 15 inches high at the withers (top of the shoulder blades). However, there are a lot of JRTs or mix breeds that don't quite conform to this standard. Generally, you won't get one over 15 inches at the withers - that would be a Parson Russell, which is slightly different. Source: See related links
i am pretty sure (eve though i do not watch it) was a Norfolk terrier
It will be 58 to 63 days after you breed her. If she is hooked up with the male more than once count the last day she would accept the stud. MAKE SURE to let your vet know well ahead of time and be prepared for emergency's ! 2-3 weeks after the first studding
The Boston Terrier breed is much like all the other breeds. My 1 year old male terrier mad my 5 year old female terrier pregnant, so I would say at about 11 months of age, they are ready.
Although I think Jack Russell's are a nice dog I wouldn't want to own one because they bounce off the walls (although the odd ones I've seen can be more sedate) but Jack Russell breeds are noted for being hyper active and they never seem to tire out. Yorkies are more sedate and little lap dogs. They prefer peace and quiet and play time. The Jack Russell is commanding things around the house and it's time for some serious training with this dog. When you say to 'stop' or 'lay down' then they should adhere to your commands no matter what the breed. Dogs need to know YOU are the leader of the pack and not them! If you had the Yorkie first then they SHOULD COME FIRST! This is the nature order of things 'pecking order.' All treats and meals should be given to the first dog in your home and then your Jack Russell should come next. I have a 4 year old Bichon Fise and a 2 year old Cockapoo and I always use this method. I don't allow my Cockapoo to try to push or order my Bichon around. I also give equal love and never just to one. I'd say you have your hands full. LOL NEVER allow your Jack Russell to torment your Yorkie! Put your foot down immediately! If it's a trial in your family please seek one on one training with your Jack Russell. There are many trainers out there that just train Jack Russell's. Another good thing for a Jack Russell (and good for the whole family) is belonging to a Jack Russell Club where you are meeting other owners and the dogs have a blast racing around through trial runs and having a complete field day and hopefully tiring out! When you do this take your Yorkie with you and hold her/him in your arms. If she/he doesn't like going then leave her/him at home with a family member.
