I am curious if you ever got an answer. I have a 5 month old cane corso (Maya) she is 72lbs already, pretty large for 5 months. I'm estimating by her 6 month mark she will be around 80lbs. Which they say to double it and adjust it,by 12 month mark she would be about 135 to 140lbs. She also is a big girl. She has a few issues when i got her at 13 weeks she had a UTI, which they had her on Simplicef for 2 weeks. Now i have her on D mannose and she is UTI free. She has a hood vulva and the vet said when they do her spay after her 1st heat if it doesn't pop down they will do the surgery to correct her lady bits. To top it off 2 weeks ago in her left eye, her third eyelid inverted giving her cherry eye, yet another surgery needed to tack it down. So 2 drops of antibiotic every 8 hours and 1 steroid drop every 12. Have you experienced any of these thing with your dog. I'm so concerned. This poor pup. Although she doesn't seem to be bothered by any of it, she is still happy and playful. I also have her on pre and probiotic gut health just to boost her immune system.
