Hi my name is keri and we are due to pick up our 8 week old toy maltipoo puppy soon but the breeder informed me that on the recent victor the vet she found out the puppy has an open fontanel. She said the vet wasn’t worried but I am. The puppy weighs 1.4pz and it’s litter mates are around 2 lbs. he act perfectly normal. Plays and eats good. Will it close or at 8 weeks is it going to stay open? Should I not get the puppy? Should I avoid all puppies from this littler or choose a different one? Thank you!!!
