What has been said so far as to time, and cost are probaly the biggest factors. Like Don said though the postives are greater.
For the most part the time really won’t be that much more now. Seeing as how your other dog is already trained. With this your other dog will help cut down the time. They will do this by training the other dog in ways you can’t. The only drawback is bad habits. They will also teach these.
Costs will go up a little. The biggest one overall will be feed. Vet won’t be that bad. At least if you have a decent vet. Most will only charge for one office visit if they go together. Yes you will have to get 2 of every now though. A lot of that cost can be made up by givng your own shots, and doing the minor doctoring on your own. We do it all here right up to our own stiches when needed. We still see our vet regularly for the other stuff. Will even purchase our supplies from them at a slightly higher cost out of gratitude for the discounts.
having more than one also means you will still have a huinting partner if one is sick, or hurt. Also gives them a buddy that helps to push the hunting abilities to new levels.
I have 5 now, and always seem to need a few more. Did have 6 unitl last friday when one of our best passed due to anaplasmosis. That was a tough one, I HATE TICKS!!! With the type of hunting I do having 12 may not be enough. When I still did a lot bird hunting always had at least 4. That way I could rotate them making sure they were always fresh.
having multiple dogs is a lot like having multiple kids. Once you get pass the first 2 it gets easier to handle.(other than costs) Seems taking care of 2 is they same as taking care of 10. Well dogs at least. I had 8 kids for an entire summer from 5-12. Other than the laundry, the overal work was about the same. At least in my eyes. My wife willmost likely tell me I’m wrong.
So go for it. Get as many as the little lady will allow!!
