I found my golden on Petfinder. It was by chance. We were looking for a golden/ golden mix. I preferred a dog that looked like a golden though it did not have to be a "pure bread". Jake has been the most wonderful dog. He was apx 18 mos to 2 years old when we adopted him last February. The vet thinks he is either "pure" golden are at least 3/4.. I had been looking at several rescue sights but in the end by chance Jake came up through a nearby "pound". So he was incredibly CHEAP. ha ha. Though I would have payed more for him. We payed $40.00.
I don't have all the figures in my head but it has not been too bad, but we have been lucky. He has not had major health issues. I have had to make a few trips to the vet for his ears. Golden's have a tendency to have itchy ears (and other things too). I have had him professionally groomed a few times (apx $50- helps w/ the shedding). I send him to 1/2 day dog daycare a couple of times a week for exercise ($7.50/day-very reasonable!) .
We feed him quality dog food so it's about $50 for a bag. Hoping that pays off w/ better health for my dog
Heartworm meds should be given monthly. (maybe $50 for 6 mos?)
You will probably need a flea/tic solution like Vectra, Frontline, etc.. (maybe $50+ for 3 mos supply?)
These are all expenses for any dog of course.. not just Golden's..
A Golden/Golden mix is a great dog!
It's good that you are asking questions. However, I hope that your parents are fully on board here. A 16 year old cannot (should not) take on the full care and expenses of a dog. If this is a "Well, it's your dog.. you take care of it" kinda deal. Don't do it. Wait until you are older (an adult). Like w/ anything (dogs, kids, homes, cars) you just don't know what you don't know.. and fixing it often takes money..sometimes more than we expect.
