conception

Question
I have a mixed breed female dog she will be 2 years old this June. This is her third heat and a stray shepherd has gotten hold of her but they were not connected very long but this is the third time this has happened. How long will it be before I will know if she is pregnant? Any information you could provide me with would be greatly appreciated Thank You

Answer
There is no way to tell until about a month.  Then a vet or other experienced person can feel developing puppies.  Ultra sound or X-rays are more certain.

Could you please just get her spayed?  We are slaughtering millions of dogs every year for lack of homes.
