Hi and welcome!
Great that you are taking Dylan to boar date. According to Suzy, getting him a cuddly humping toy will be the best thing you can do for bonding boars; hopefully, the toy will absorb any excessive humping that might ensue when boars get excited. Thankfully, the vast majority of boars is great with babies since they are not a threat to them in any way. Some adult boars can be such cute "uncle pigs" indeed!
If you want to get an idea, have a look at Suzygpr's boar dating thread (she runs a rescue in South Wales):

When bringing Dylan and his new friend home, please have the cage thoroughly cleaned, including walls/grids/mesh and any furniture. If you can, rearrange things so the space is as neutral and new for either piggy. Make sure that you have got everything in twos - hideys, bowls, water bottles, etc. If necessary, spaced well away from the other same item, so noboar can go possessive.
You will want to give more pellets to a growing piggy than you would to a mature adult, so you will have to find a compromise for the next few months. Ideally, youngsters will need constant access to pellets until they they have got most of their size at 6-9 months. From then on in you can very slowly reduce the amount to the handful they will need as adults from 12-15 months onwards. Otherwise, youngsters don't have any different requirements. Enjoy the baby antics while you can - they grow up so fast!
I am sure that Helen will have told you what she expects space wise. If you need tips for cheap cages or hutches, please post in our housing section.
I am very much looking forward to pics of all your boys! All my piggies are rescues, too; one of them has been rehomed from the predecessor of the Potteries Rescue. I have just dated my two cataract lady at a rescue that has neutered boars for them to choose their new husboar last month. So far, piggy dating has always been a huge success for me and any (usually bereaved) piggies. Best of luck for you and Dylan!
