Oh me, oh my!
A 10-month-old Boxer (Zoe, formerly known as Lexy, who we must still call that until we get her somewhat used to the household) who has a limitless supply of energy being dropped into a household with a 10-year-old reclusive Lab/Dane mix (Pepper) and a 9-week-old Boxer (Wash) is ... well ... exciting to say the least.
The two youngest like to play but Lexy/Zoe overpowers the baby to the point where he is constantly seeking out shelter (under couches, under chairs, between peoples' leg) from the relentless onslaught of fun, Fun, FUN!
The venerable oldster had retreated semi-permanently to his bed in our bedroom to escape Wash. However, when Zoe/Lexy showed up we were delighted to see that he, surprisingly, was interested. All of us have experienced a bit of disorientation when he and she come running into a room as our brains automatically reference the previous pair of Daffy and Pepper and then must shake free to adjust to Lexy/Zoe and Pepper ... and their shadow, Wash. Clearly, Pepper feels that Boxer familiarity also. He was interested enough to follow her outdoors and then to assume his post on "Pride Rock" (also known as the top step into our sunken living room) to keep an eye on proceedings. They occasionally do a sniff-down, "nice to meet you" ritual. Biggest of all, Pepper actually has growled and bared his teeth at Lexy/Zoe when he had a bone and she tried to take it. Perpetually gentle and allowing himself to be bullied by any dog but Daffy, his self assertion was cheered and praised by the family ... and he is accepted by all as king of the pack.
She is a really sweet dog, with good manners (and house trained!) except for the occasional lapse of following someone up onto the furniture in a fit of enthusiasm. At which reprimands, she often just proceeds over the back of the couch onto the other side.
It is like a three-ring-circus but we can already see her quieting down occasionally. If we all live through this huge wind of energy she is injecting until she adjusts to everything, this is going to be tons of fun for everyone in the household. Already we have been laughing our heads off most of the time.
