My Jack Russell Terrier is pregnant........

Question
I have a Jack Russell Terrier that was bred in June to another Jack Russell. She had 7 her first litter.  My question is will she more than likely have another big litter or do the litters get smaller with each litter?  We bred her her 2nd heat and then waited until this one. She is 3 yrs. old.  

Thanks,

Lois

Answer
Hi Lois. If she had a large litter last time, and you keep her healthy this time, then she is most likely going to have another good sized litter. 3 years old is still young, and it sounds like you waited a good amount of time before breeding her again. She very well could have a big litter this time as well. Good luck!
