hello ive recently took on a nice young collie\grey thats 14mths old and he had a retained testicle, i researched a bit and found prob best to get it removed... was wondering if any of you folks have had dogs with this condition and how long after surgery you were running them again ... its over 2 wks now and vet says he should be ok within a few days (has had gentle exersize since the op) ..i understand its quite an invasive op and some muscle is cut into to remove it, this is what concerns me given the exertion he will give when working lamping any info experience appreciated cheers
