We have an ancient rottweiler. He is 12 yrs old, and in rotties thats pretty old. Another thing with rotties is-they are strong headed. I've had more than one. Now Jake has slowed way down in the last couple yrs. Stays home, lays around the yard. Never botherd the chickens or anyone else. Unless your a cat-he always hates cats! Heres the problem: Down the road there is a young boxer, male 1yr old I think, certainly not more than 2. Their in LOVE! We can't keep them apart! Their both males, but they wont quit!!! It's gotten ugly. When their together(we've never had to chain our rottie, the boxer has always been chained since they got him) they hear/see/smell only each other. Their obcessed, posessed. They will get aggressive to persons trying to interfer. They want each other in a bad way! We do not know whats up??? We have resorted to chaining our dog, and patrolling the yard. The boxer gets lose ALOT! One good thing-since the boxer only has eyes for our rottie, he doesn't even notice our flock-YET! Any opinions??? And yes I can see the humor in it, twisted as it may be.
