Just wanted to do the courteous thing and introduce myself before diving into your forum.
I have just adopted a dog from the pound (where I do some volunteer work) and we are slowly getting to know each other. He is a 4(?) year old Mastiff X, desexed on the day I picked him up! We have named him Jacob. We had planned on adopting a dog since we bought our house together a year ago, and I had been reading everything I could get my hands on for the previous six months, but still, I'm not sure if I would ever say I was entirely ready! Sometimes you just have to go with the heart. Neither my partner nor I have ever had dogs (well, not as adults), and so we are aware we have bitten off a lot, but we are both dedicated and loyal (tenacious?) people, and we are commited.
It has been a fortnight so far, and it is fascinating watching Jacob starting to relax and show us his playful side. Of course, I expect we shall also see some things that we would prefer he didn't do (such as a penchant for chewing beds and blankets), but we're taking it slowly, rewarding what is good, and ignoring as best we can what isn't. We took him to his first Dog Training Club night this week, which was... interesting. And I have been researching trainers in my area because I definitely want to work with a professional to ensure I do more right than I do wrong
Anyway, I am sure I will be here with plenty of questions and searching through your posts for the many things that we will experience in the years to come.
