Just keep trying, That is sad to think he might be going to another home just because he isnt 100% housetrained, which I have read on here is really good if you can get them 100%. If you dont have the time to train him properly then use belly bands when he has run of the house. My dixie is 6 months and not near potty trained and my peanut is only 3 months, they both have accidents..and I expect it, they are just babies. .I would never think of getting rid of them for that reason...I couldnt for any reason, they are a joy and I love them to death. .I knew beforew I got them they are hard to housetrain, I am not an expert this is just my opinion.....good luck to the little guy
