If you bring up your little donkey as I have advised, I think you will find it advantageous to have it regularly cleaned like a horse, and you need not be afraid of your groom hurting it with the curry-comb, as the skin of the ass is remarkably thick. It must, however, be broken in and regularly trained before you venture to ride it, as you will find it full of spirit. The usual age for breaking donkeys in is about three years, but, as yours will be rather precocious, I think you may begin when it is about two years old. Asses and mules are admirably adapted for mountainous countries, as their hoofs are long, and furnished with very sharp rims, leaving a hollow in the centre like the ring of a patten. The hoof of the horse, on the contrary, is round and nearly flat underneath. It is the peculiar formation of the foot that renders mules so valuable in Spain, where there are so many mountain ridges to be climbed over; and I have been told that in Spain sixty guineas English is by no means an uncommon price to be given for a good mule. You must not form any idea of what your donkey will be from the specimens you have seen at watering places; for no doubt you remember what the Irishman said of a Ramsgate donkey--"that it was the hardest-worked creature in the universe; for it was carrying angels all the day, and spirits all the night." Your donkey, on the contrary, will spurn the ground beneath him; and I expect, when I come to see you, to find you cantering over the downs upon it with your little dog Fair Star running by your side. Haying mentioned your pretty little spaniel reminds me that I promised to give you some hints on _dog management_, and I think I cannot make a more useful conclusion to my letter. In the first place, it is generally allowed by the learned in such matters, that whenever a dog becomes very fat, which lap-dogs are very apt to do, it is sure to have that distressing disease called the _canine asthma_. How many poor dogs have I heard wheezing and panting with this complaint, and how earnestly have I longed to become their doctor! When the disease is of moderate standing, very frequently a little abstinence, and feeding regularly, but only at stated times, will give relief; but, if this is not enough, one grain of tartar emetic with two, three, or four grains of calomel, according to the size of the dog, will effect a cure. _Sore eyes_ are for the most part produced by some derangement of the stomach; and, for their cure, putting a stick of sulphur in some water within reach of the dog will generally be sufficient. The water should be changed every day, but the same piece of sulphur will do for months.
