Jealous issues with your staffy

i was just wondering if any of you have jealousy issues with your staffy(s)? Harley gets so jealous if i am patting Mia or having some time with her(Mia is a 5 year old bordr collie x jack russell),it's like "u can't spend time with her your MY mum".

I know what happens when Mia gets jealous(so does my arms,legs etc)i have the sares to prove it, i don't want Harley to get attacked by her because he's jealous of me spending time with her, i could be patting both at the same time and he still gets jealous and if Mia is lying or sitting next to me he will force his way in. He growls when he does it.

How do u deal with this situattion if u have encountered it?

I haven't encountered it as only have the 1 dog, how long have you had them both for? And who came first?

Janey, i have had Mia for 5 years and Harley for 14 months, it's like i can't spend time with Mia at all. They both get loved and spoilt as best i can.
