We have 5 cats and 2 dogs, if it was up to me I would have more dogs.
Everyones situation is very different, money, time, patience, etc.
However when I think about adding another member, it's not taking lightly, it can't, it just doesn't effect you, it effects the pack, your significant other, the pocket book, etc.
Since I don't work, my schedule is very flexible, and I know that dogs like to have a schedule, so I created a schedule, and I stick with it (even though there is flexibility).
Jasper has also saved me from lots of negative aspects that I have had in my life, it's a fact that animals add years to your life, however it's sad to me to see you feel this way.
Your feelings will project onto Quincy, no matter how you look at it, he is also at a tough age, everything seems difficult during this time period.
Jasper has Elbow dysplasia, I have spent over $10,000 on him (surgery, rehab, meds, shots 2x a month, training, etc), but money is no object when it comes to certain things.
We don't have children, and if we did, I would be the same way.
Never make a rush decision, think things out, do things the proper way, everyone makes a mistake, we are human, we aren't perfect.
It's nice to see that you have shared this, because some people could easily want to flame you for your feelings, but that's their opinion (because they care about the Quincy's well being. It shows you can take the heat, but you want to do whats best for all involved.
If you do decide to give him up, try friends or family, rescue, just someone you can trust.
Please take no offense to this, but sometimes people just don't know what they are getting themselves into, until they do something, then it backfires (example, family gets puppy at christmas, then 4 months later its in the pound
(that's a big problem I have).
No one said it's easy to raise a puppy, or a child, but responsibility and owning up to your actions is what it sounds like what you want to do.
If you got Quincy from breeder, call breeder and see if they would take him back (it happens).
Just make sure whateveer you do, it's what is best for Quincy, he deserves at least that.
You have started the process of in right manner, putting it into words, and on this forum.
Just make sure you finish the job, and either he gets the love he deserves from you, or he goes to a loving home.
The ball is in your court, now lets see how you handle it, IMO it will telll me alot about your charactor.
Good luck to you, and for now on, be patient, loving (not say you not), give some time, he is only 8months old, you are his guide, his leader), he looks for guidance from you, so make it happen, one way or another.
Just don't banish him, dogs have a pack mentality, and they don't like to be banished from the pack.
PM me if I can help further.
