New puppy

[Acer11]

Please can anyone give me some advise, I lost my previous dog a year ago at the grand old age of 12. Was completely devastated and waited a year to get another one. Along came my new Puppy Alan who is a schnau-tzu. He is a rescue from a puppy farm. I got him at 11 weeks and he is now 16 weeks. Is it normal to have the rollercoaster of emotions from sending him back to madly in love. I do think he is more schnauzer than shitzu as he is full of energy. Started puppy classes with him on Sunday and he barked a lot *. I have started walking him and he’s doing really well but he does have very mad moments and bites ankles and shoes, feel that I am constantly on high alert. I don’t work so feel quite islolated at the moment. On a positive his potty training is coming along well and he sleeps through the night. Think I would just like some info about terriers as I think that is his dominant gene. This is my first time on mumsnet and would really appreciate feedback as it’s starting to get me down. Thank you 🙏

I think you probably should have looked up the breed before getting the dog tbh.
Have you had a puppy before OP? They are usally full of energy, barking, play a lot, need potty training, etc. It's a lot of work. Puppy farm rescues don't usually have the socialization that others dogs might have had. All of the things you mentioned can be improved with a lot of hard work. Puppies need training. The puppy classes will help. Any specific behavioural problems I would ask them for advice and they should be able to help. I think exercise and socialisation is key at this point as well, so keep going on those walks.
Good luck!

You should post on The Doghouse section of PETS as you'll get more traffic. There is a puppy thread there too.
