My name is Jack -JJ!

JJ, AKA;Jack; he is 8 years old
Is a very smart dog, trained to sit , lay, follow commands,
He is on schedule and aware of schedule - he understands human words
Loves attention, loves to have companion, loves walks.
He was bottle-fed as baby had lots of love and attention.
I was his only owner,
He is getting up there in age and showing signs of it.
He will still fetch ball and has spurts of energy, but not all the time. JJ recently has been experiencing some behavioral issues out of the blue, he forgets who we are when startled, he doesn’t know who we are until he visually sees us
He gets aggressive at times, then snaps out of it.
JJ needs a companion and a home without children, he may be ok with other dogs , he has been with our 2 others just fine and visits with family dogs. Fenced in yard, if not supervised
He needs someone to pay attention, respond to his special needs at this point.
He is being rehomed because of his changes in behavior that I cannot manage.
