Hindi / Urdu कुत्ता kuttā (dog) is related to Prakrit kutta कुत्त (= dog) which in turn is related to Sanskrit कुर्कुर Kurkura. Though the only word for dog in Rigveda is śván श्वन् >> Pali sā & in Prakrit by sāṇa. Research suggests that kurkura is perhaps a non-Indo Aryan word.

The oldest known reference to a female dog is found in Rigveda. Sages belonging to Indra and Angira clans sent a female dog named saramā सरमा to successfully find the cows that were stolen & hidden by Panis. She is also known as देव-शुनी, devaśunī.
The name sārameya सारमेय became synonymous with dogs, possibly the good breeds. Sanskrit Thesaurus अमरकोशः Amarakośa mentions sārameya when it lists the 7 names of dog of India. The seven names are –

🐕 kukkura कुक्कुर

Interestingly the 1st European dogs were brought to India by the Portuguese traders. Later English diplomat Thomas Roe brought Mughal emperor Jahangir 2 mastiffs, after his liberal predecessor Akbar had imported dogs from Afghanistan & made the earlier Islamic prejudice against dogs disappear. Jahangir was so much pleased with the dogs that he fed them with his own hands, & gave them four attendants each to fan them during the hot season, & had them carried about in palanquins.
On 9 January 2005, four commemorative postage stamps were issued by India Post (Government of India) for four indigenous breeds of Indian dogs i.e. Himalayan Sheepdog, Rampur Hound, Mudhol Hound and Rajapalayam.
