I have reserved a puppy (border terrier) which is now 5.5 weeks old, we are due to collect him at 8 wks. The breeder called yesterday to say the dam had mastitis which caused infection in the pups and they were put on antibiotics and hand weaned. The breeder says they are all well and recovered. Is there any advice on what concerns, if any, I should now have about the pup in terms of health, development, etc ? I'm wondering about how this could have had an adverse affect on the puppy. Any advice much appreciated, thanks.
