One into whose ears the name of Lord Krishna has not entered is no better than an animal.

Srimad Bhagavatham 

तरवः किं न जीवन्ति भस्त्रा किं न श्वसन्त्युत ।

न खादन्ति न मेहन्ति किं ग्रामपशवोऽपरे ॥

[ 2.3.18]

Are not the trees living?  Are not the bellows used in the smithy breathing?  Are not  the cattle in the village eating  and excreting? [ All these activities are common to man and animals]. 

श्वविड्वराहोष्ट्रखरैः संस्तुतः पुरुषः पशुः । न यत्कर्णपथोपेतो जातु नाम गदाग्रजः ॥

[2.3.19] 

Man is considered better than the dog, the cat, the pig, the camel and the donkey.  But one into whose ears the name of Lord Krishna has not entered is no better than an animal.
