Hi there! My female dog is 14 lbs and my male is 18 lbs. Is he too large to breed with her? I have raised large dogs before, but not small ones. Thanks!

There are probably close enough in size to not have any issues, but it is difficult to say with any certainty. Being mixed breeds, it is possible there may be some possibility that the pups could be larger than the mother. If you choose to proceed, after vet checks of both dogs, have the mother x-rayed about a week before her due date. Your veterinarian should be able to determine litter number and size then may predict more accurately if surgical intervention will be necessary.
