How do I cure the relapse in my dogs behavior? Eating off the table, going inside, ignoring commands?

My five year old dog has recently relapsed in behavior. She's always been very well behaved and recently she has gone to the extreme opposite. she's always been housebroken and recently she's been soiling our bathroom while we are gone and asleep- we take her out before bed, in the morning, and before we leave. She's also been helping herself to table food. Today I set a plate of pizza rolls on the living room table ran to the bathroom and came out to find the entire plate gone. when we take her out she's been taking off through the neighborhood and ignoring commands to come. similar experiances for the last 2 weeks. What do we do?How do I cure the relapse in my dogs behavior? Eating off the table, going inside, ignoring commands?
sorry but one of the reasons might be that yur dog is getting old! that may only b one reason though there can b millions of reasons - recently my friend's dog was doing the same things. yur dog might b upset with yu or feeling sick . Check the vet , but if u dont want to spend ur money on dat well when she does bad thing DO NOT YELL @ her it only makes it worst , scold her but without yellin.You might just b going through a face though ! just shoe affection and that yu care - yes it might seem as if it doesnt matter , but it does... other than that i think yu would have 2 have an experts answer :(

good luck though!

my bet would to be teach it and give it a reward for being good and obeying and if it doesn't scold it like: Bad boy/girl. and if you go on walks with it make it use a leash until it gets the hang of walking with you and doesn't try and run away.
