Dog needing rehomed

Nacho is a 3 year old yorkie/pom(apparently ) . He has behaviour issues and altho I have him around my children he needs to be rehomed to someone with older kids or no kids .he can be reactive.Ideally he would be with someone a little older or elderly as he is definitely a lap dog . He will nip if scared . It takes him a long time to warm up to people. He is honestly the most loving little dog just wants love and to be on your lap but he also thinks he is the boss . Not fully potty trained . If taking him you will need to come and take him on a few walks so he can warm up . He’d suit a home with no other dogs . His behaviour is definitely improved when he is the only dog . He is a good dog just has issues and needs someone who is willing to give him the love he deserves. He likes to be round other dogs to play . He is neutered ,microchipped and injections are up to date
