From John Henry Baldwin’s The Large and Small Game of Bengal and the North-western Provinces of India (1876):

In general appearance (as already mentioned when speaking of the panther) the Indian leopard so much resembles the panther that they are often confounded, and to the present day classed by some as one and the same animal. [NB: Panthers are just the black color phase of leopard]. In the Himalayas the leopard is very common, and a perfect pest, continually carrying off dogs close to the outskirts of our hill stations. A dog that is in the habit of leaving his master and wandering from the foot path, when travelling in the hills, is almost certain, sooner or later, to be carried off. I have known of many fine sporting dogs taken when shooting pheasants and chikor [chukar].

Leopards are in the habit of watching foot-paths, from some hiding place above, whence they can view everything that passes. As soon as they perceive a dog or goat loitering behind or astray, they steal rapidly and silently down, and before poor ‘ doggy ‘ can join his master, or an unfortunate goat his comrades, he is seized by the throat and swept off the path without having time to utter a cry or offer the slightest resistance. A good stout dog is almost a match for a leopard, if brought face to face with him on open ground, but the cunning cruel cat creeps up and buries his fangs into the neck of his prey when he least expects him, and once in the fatal grip, a dog or any other creature hardly ever escapes. I remember, however, a plucky little terrier belonging to Colonel D—s of the 37th, making his escape from the clutches of a leopard, and returning to his master with a wound in his throat.

Two moderate-sized setters, the property of a gentleman at Mussoorie, turned on a leopard which attacked one of them, and speedily got the better of their assailant. They so worried the beast that it was unable to make its escape, and was easily dispatched.

It is not uncommon for the Thibet sheep dogs [Tibetan mastiffs]—large powerful animals (something like the Newfoundland breed with heavy ‘jowls ‘) and specially retained to guard flocks and herds—to be carried off by leopards; sometimes these dogs escape through wearing broad spiked iron collars. I remember seeing a collar deeply indented by the teeth of a leopard; the wearer had escaped with his life after being dragged some distance, but was grievously wounded.

Leopards are seldom seen in the daytime. I have only on three occasions seen them in the Himalayas, although I have travelled and wandered a great deal in our hill ranges; yet they are common enough.

The first thing that takes your eye in the early morning as you leave your tent, is the scratch on the turf from the foot of a leopard; if you examine the outskirts of your tent, you will likely enough find his ‘pug,’ where he has been sniffing under the canvas for ‘Dash’ or ‘Juno;’ and the sap yet running from a neighbouring tree shows that he has only an hour or two before been stretching his claws on the bark. I had a setter whose mother had been taken by a leopard, and who himself had had more than one narrow escape. This dog always slept on my bed, and more than once has awakened me on a dark night by his growling and trembling all over, and nestling closer to me, evidently from fear of some brute close at hand, probably a leopard. The first expedition I ever made to the hills I lost a pet dog named ‘Snip,’ carried off by a leopard; he was by no means a well-bred dog, rather the contrary; a thick-built brown terrier, rather bandy-legged, curly-tailed, with a pair of prick-up ears, and brown intelligent eyes. I bought him from a soldier in the barracks at Allahabad when a pup, for one rupee, and though not a valuable dog, he was a prime favourite of mine. For several months this poor dog was my only companion; we always shared our meals together, and sometimes both Snip and I had to put up with very ‘short commons,’ and retire to rest after only a scanty meal. One windy wet night, having collected sundry scraps, and filled a plate principally with rice for my dog, I placed the dish at the entrance of the tent, and soon Snip was in the full enjoyment of his meal. Having tied a lantern on to the tent pole and lit a cigar, I took up a book and lay down on my bed. In another minute I was startled by the sharp cry of my poor dog, and jumping up, I rushed out of the tent. I could see a dark object making off: catching up a lighted piece of wood from a fire burning outside, I hurled it at the animal; but although the sparks from the burning wood striking the ground almost between the creature’s feet showed it to be, as I expected, a leopard, the animal would not drop his prey. I ran after it shouting, but the brute disappeared in the darkness down the face of a steep decline. I went back, got my gun, a lantern, and two men with torches. We searched everywhere, called the dog by his name and whistled, but in vain, and in half an hour we returned wet through from a fruitless quest (pg. 68-70).
