How can I reunite my german shepherd and beagle after they fight a month ago?

We tried to reunite them today and it kinda worked but we separate them by using a fence and put the beagle in it where the GSD wont get her. The shepherd is 9 months and the beagle is a year and a half

dogs dont carry grudges!

If you spay and neuter them this should'nt happen,GSD are great dogs and the beagle also tho a little hyper.If you want the problem to go away this is your first step

try having them play in the same room-- one person plays with one another with the other, then have them play together

neuter them. then get them together but supervise so if they fight, scold them. praise them if they are together and being nice to each other.

take them to the park to playtired dogs don't fight, no bones, no treats, no food around each other till they acept each other, there might be some growing and snarling and a skirmish but they need to determine who is dominate.keep an eye on things, be ready to intervene if things get serious, and don't severely punish the winner and don't reward the looser. You need to treat the dominate dog as the dominate one, food and attention first theres a ton of articles online, about having two dogs that fight

Just keep doing what you are doing. Keep introducing them through the fence and once they begin to lose interest of each other, introduce them on leashes on neutral territory. If that goes fine, walk them together home. If one happens to try to dominate the other dog, it's your job to stop the dog. This will show the dogs that you will not tolerate any aggression. Some common mistakes people make is they feed the dogs together and leave toys around. These items trigger the pack drive in dogs.
