Help Dexter see again

So we had to have our older dog Obi put to sleep which was one of the hardest things we've ever had to do. Then the day after our 5 year old Dexter started having trouble again with his eyes, two years ago he was diagnosed with having cataracts in both eyes, only being 3 years old obviously we didn't expect this, the vets were able to fix one eye which cost 3 grand, but two years later he's developed glaucoma in it, basically he will need to have his eye taken out! There's maybe some good news and that is they may be able to fix the other eye so he can see long distance, all this is going to cost over 4 grand! We were told by a few friends we should start a go fund me account in hopes to help with this unexpected bill! Normally we wouldn't even consider asking but as it is we're having temporary finacial issues and we don't have all the money right now! I've given to causes like this and know they work, I'd just like to thank anyone that can even donate anything no matter how little!
