As you can imagine, this is near to my heart!!
Rabbit was born 28th September 1979...at 5.30 am and it was copulating well cold, I can tell you.
And raining.
His problem is the reverse to yours, he has no back teeth...thanks to an Equine Dentist (who trained in the states, and was actually very very good...BUT...) He ground them down, completely forgetting Rabbits age, and not taking into account the fact that they were no longer growing, in spite of my standing there telling him!!!
Still, can't undo it, can I??
Now I am in heaven, Dentist wise, as all the Vets in my practise are qualified Dentists and Farriers....coz I now have the Royal Veterinary College as my practise...on call any time of any day or night, and twenty minutes away.
Any time a horse needs to go in for any procedure I get it cheaper...Ray!!!
Anyway, Rabbit has been unable to eat grass or hay for three years, now, thanks to that, and I now boil his grain...I wonder if that might help your boy???
I just have him on straight barley, and I pop it in the microwave in boiling water, for five minutes and feed it as soon as it has cooled, I put it in with his soaked Beet Pulp (five cups) and soaked Alfalfa pellets (five cups, both dry measure BTW), and I also soak grass chaff (not Alfa A...a grass version of it, much shorter chop) and mix this in as well....he will sometimes leave the chaff, if he is not up to it that day, but he scoffs the rest of it down!!
He still pretends to graze, and is very good at chewing it up and spitting it out, I am touching wood as I tell you so far he has not had a choke incident.
I am so heartened when I hear of people taking on these senior citizens and looking after them so well, Rabbit has been with me all his life, he will die, hopefully with dignity, on the field that gave him birth, but it is so easy for one to slip through the net, so Bless You, for doing this, and I am so pleased he has rewarded you with a foal!
Rabbit had a daughter this year, he has bred one mare this year, we shall now wait and see!!
There is plenty of life in these "Old Dogs"!!!
