I dont know much about them. but Blaze plays with one who is 180ishlbs. Koda is MASSIVE, Blaze loves playing with him, as he isnt as agile and is alot slower lol. But every time Blaze is done playing with him, it looks like he just got abath, as Koda drolls TONS all over blaze, its nasty lol But worth it as they both love each others company, nothing a quick swim in the river wont fix lol
