i have a small farm (25acres). i only have cattle at this time. i will be getting sheep when i redo my fence. i have 10- 2 yr.old heifers, 1 very nasty young bull,and one 5 yr.old cow with 4 mo. calf. they are all charlios. i don't "need" another dog to help me with the cattle, but i love watching them work. i have a little red female a.c.d. (8yr.old & 29lb) that is doing great. i got her from a shelter in naples, fl. about a year ago. it was to be her last day before they put her down. i saw her and just could not leave there without taking her with me. she is very prey driven and will go head to head with my bull. she is pure acd, just alittle small for the breed. very hard headed. she will not stop until the cattle are where "she" thinks they should be. i would like to have a bc, everybody says that they are so much more trainable. will a border collie get face to face with cattle or are they more into staying back and hope'n that the cows will move? will a bc want to be at my side all the time that he is not working or do they go lie under a tree. i don't know much about their personality. thanks for any info that you can give me... virg
