Hi everyone! I need help, please.
I posted earlier about my 4 month old male lab mix. The pound said they thought he was a lab/golden retriever mix... but seening some pit bull mixes, he has the SAME color markings with white patches as some of those.
He started with nipping and pulling at our clothes (jeans & sweaters, etc) and going for our hands as if we were playing. At first, he would stop if we shook a can with a few pennies in it and saying "NO" but now, nothing. He'll still try to bite us.
We have tried to do the whole "OUCH" and "YIPP" thing, but he doesn't care. We tried to leave the room for a few minutes after saying a firm "NO" and no attention... we did this for a solid weekend, at least a good 50+ times over a few days... still would go right to trying to bite us. We tried a few days of putting him in a "time out" in his crate for 10 min at a time... but it just seemed like he ended up spending most of the evening in there with only a few min out of the crate before he'd bite us again.
I noticed that he will work himself up out of the blue and start to bite furniture or our rug, then when we tell him "NO" and give him another toy, he gets pissed. If I pull him away from our rug and try to switch it with a toy, he'll try to bite, sometimes "play bark" it seems, and continue to try to go for skin. This same behavior comes when he'll stay by the baby gate that separates our house, since we don't want him in the bedrooms with our two cats. He'll lay down right in front of it, and if he sees one of my cats he'll start to bark and dig at the ground... if we tell him "NO" or try to pull him away from it to go play with a toy instead, he'll instantly let out a sudden bark and start to bite the air in our direction.
He gets fed 2 times a day, and goes on long morning and evening walks. Sometimes I'm on my rollerblades so his walk often leaves him running and working for long periods of time. He has plenty of chew toys and bones to play with, and often try to change the play we do with him to fetch, no tug o war. I train with him as well teaching him to sit and down, etc.
We're just worried about this aggression and fear we can't afford a behaviorist. I have read countless forums and all it seems like I can find is the whole bite inhibition "OUCH" thing or time outs/leaving the room stuff. It doesn't work for me, neither does spraying the rugs/couches with sour apple or bitter spray (he'll continue to bite on it regardless).
Any advice would be greatly appreciated!!!
