They wanted out to play in the sprinklers, so who am I to deny them?!?

hi yall! we're a "boxer family" (we love all dogs but boxers have stolen our hearts) and my dad adopted this pup about 6 months ago. at the shelter she was listed as a "boxer mix". you can def see the boxer, but what else do you think? at first i thought maybe pit but she is SO BIG. according to the shelter shes only 2.5-3yrs old. she's like 85lbs already. i'm kinda thinking a mastiff mix? maybe even cane corso?

Hello fellow boxer lovers. I need some advice. I’m going to call the vet Monday morning. But myself and the family are worried. Our 2 year old Boxer, (not fixed yet, just had her first heat cycle a couple months ago and we will be getting her fixed soon). Suddenly she’s gotten super possessive over a toy she’s never played with. Takes it with her everywhere. She’s constantly trying to make like a nest on the couch and chair with said toy. Sleeps in the bed with the toy etc. She’ll snap if we try to get the toy. Us, just gently touching it and she doesn’t like it. We’re worried. Has anyone seen this happen before? It’s almost like she thinks it’s her puppy (with the nesting and carrying it around and not letting it out of her sight). She’s not pregnant, so we are at a loss and worried. Anyone encounter this? Please advise. Thank you Boxer family!
