So interested to see that reply - just on the phone yesterday with the vet who told me that there was some controversy about whether neutering would stunt head development, but he's usually very cautious. We originally had planned to wait until Bertie is a year old, but he's developed cherry eye and so next month he'll be 10 months and he'll have both procedures at once. I can't imagine his head getting that much bigger in two months. He will also do an ultrasound because when Bert pees a lot of air accompanies it. No distress or sign of infection, just always had this funny pneumatic noise when he urinates. Anyone else experienced that?
