We have two younger cardigan welsh corgi 1/2 brothers. Ragnar is now nearly 16 months old and Kelso is nearly 10 months. They are unneutered. We were going to get Rags done at 1 year, but then thought we should wait and have them done together so the are both recovering and not trying to play and ripping stitches etc. They get along fantastically most of the time. They cuddle, Ragnar cleans his little brother, they've finally mastered walking in tandem on the leash. They play, they share food from the same bowl--although each has his own bowl, they invariably share one, then move to the other. They especially like tugging toys and will rip any stuffed toy to shreds through tug of war. This where the problems seem to start, however. They will be playing happily and then one will want the whole toy. They get carried away and Kelso is bearing the brunt of it more and more. It seems to have really escalated in the past 2 weeks and today, Kelso had a large scratch on his cheek--it bled a lot which was upsetting, but it's not deep, just faces bleed a lot. I should also add that Ragnar is not an aggressive dog otherwise. Both are very sweet natured. They will let us take things out of their mouths and if we tell them to drop something vile, they do. Ragnar loves other dogs and always wants to play with them. He doesn't do this to anyone but Kelso. And 98% of the time, they're wonderful buddies. What can we do, short of not letting them ever have toys or chewies, to stem this? We separate them (we sometimes have to use the squirt bottle), and make them calm down. We take away the problem toy. But my hope is that they will learn to just play like normal dogs. Would neutering help? Are there behavioral exercises we should be putting them through? Please help!!!!
