Hi there everyone, background really quick on me.. I'm 37yrs old I've had a dog practically my entire life, 2 german shephards, 1 golden retriever & currently a Chihuahua/Mix & a Jack Russel/Mix. The Chihuahua was the 1st we got & the jack a yr later, also I was the one who suggested we get a puppy, then a yr later suggested 1 more to keep Madison/Maddi company. Fast forward 3 yrs and all is well, I'm the one who basically takes care of them, walks them, feeds them, etc... Now these dogs couldnt be more polar opposites in personality, Madison the Chihuahua LOVES people & other animals, LOVES the heat & walking, Peanut the Jack barks at people & other animals and is also aggressive, she dosent care much for walks ESPECIALLY in the heat!!! I'm talking Madison is pulling all the way in front of me & peanut is lagging behind the entire walk!!! So sometimes when it's hot like it's been, I'll take them both out, but come back & drop peanut off at home to take Madison out for another 5min or so. When I do that, ill make it a point to come back & play with Peanut throwing the ball for a bit & if maddi wants to play too at the same time, we will... My gf thinks I'm playing favs & freaks out on me for this... YET, she will play SOLELY with peanut throwing the ball & maddi just got fed up with her basically ignoring her bc Maddi is harder to play with. She dosent always want to come back with the ball or toy, so she'll come back but wants you to get another toy or something, so she just lays there and dosent even try anymore. But am I playing favs with dropping 1 dog off to take the other for 5min bc the 1 hates the heat?? Also mind you this only happens once in a while, it's no wheres close to being a normal thing... ide luv your input
